Structural engineers analyze, design, plan, and research structural components and structural systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work takes account mainly of safety, technical, economic, and environmental concerns, but they may also consider aesthetic and social factors.
106-670: The Great Exhibition of the Works of Industry of All Nations , also known as the Great Exhibition or the Crystal Palace Exhibition (in reference to the temporary structure in which it was held ), was an international exhibition that took place in Hyde Park , London, from 1 May to 15 October 1851. It was the first in a series of world's fairs , exhibitions of culture and industry that became popular in
212-484: A Civil Engineer , but some states require licensure specifically for structural engineering, with experience specific and non-concurrent with experience claimed for another engineering profession. The qualifications for licensure typically include a specified minimum level of practicing experience, as well as the successful completion of a nationally-administered 16-hour exam, and possibly an additional state-specific exam. For instance, California requires that candidates pass
318-462: A curtain wall system that allowed the hanging of vertical bays of glass from cantilevered beams. The Lily House was built specifically to house the Victoria amazonica waterlily which had recently been discovered by European botanists; the first specimen to reach England was originally kept at Kew Gardens , but it did not do well. Paxton's reputation as a gardener was so high by that time that he
424-540: A better future. Europe had just emerged from "two difficult decades of political and social upheaval," and now Britain hoped to show that technology, particularly its own, was the key to a better future. Sophie Forgan says of the exhibition that "Large, piled-up 'trophy' exhibits in the central avenue revealed the organisers' priorities; they generally put art or colonial raw materials in the most prestigious place. Technology and moving machinery were popular, especially working exhibits." She also notes that visitors "could watch
530-478: A comparable size. His submission was budgeted at a remarkably low £85,800. By comparison, this was about 2 + 1 ⁄ 2 times more than the Great Stove at Chatsworth but it was only 28% of the estimated cost of Turner's design, and it promised a building which, with a footprint of over 770,000 square feet (18 acres; 7.2 ha), would cover roughly 25 times the ground area of its progenitor. Impressed by
636-410: A controversial issue that had been a major sticking point for the vocal anti-exhibition lobby. Paxton's modular, hierarchical design reflected his practical brilliance as a designer and problem-solver. It incorporated many breakthroughs, offered practical advantages that no conventional building of that era could match and, above all, it embodied the spirit of British innovation and industrial might that
742-617: A description of the dinosaurs was entitled: 'Geology and Inhabitants of the Ancient World. Described by Richard Owen , FRS. The animals constructed by B.W. Hawkins , FGS'. In the central transept was the 4,000-piece Grand Orchestra built around the 4,500-pipe Great Organ. There was a concert room with over 4,000 seats that hosted successful Handel Festivals for many years and August Manns's Crystal Palace Concerts from 1855 until 1901. The performance spaces hosted concerts, exhibits, and public entertainment. Many famous people visited
848-419: A grid 77 modules long by 19 modules wide. As each module was self-supporting, Paxton was able to leave out modules in some areas, creating larger square or rectangular spaces within the building to accommodate larger exhibits. On the lower level, these larger spaces were covered by the floor above, and on the upper level by longer spans of roofing, but the dimensions of these larger spaces were always multiples of
954-521: A grid of cast iron beams, which was held up on slim cast iron pillars. The resulting cube, with a floor area of 24 feet (7.3 m) by 24 feet (7.3 m), formed the basic structural module of the building. By multiplying these modules into a grid, the structure could be extended virtually indefinitely. In its original form, the ground level of the Crystal Palace (in plan) measured 1,848 feet (563 m) by 456 feet (139 m), which equates to
1060-620: A key inspiration. Paxton left his meeting with Cole on 9 June 1850 fired with enthusiasm. He immediately went to Hyde Park, where he walked the site earmarked for the Exhibition. Two days later on 11 June, while attending a board meeting of the Midland Railway , Paxton made his original concept drawing, which he doodled onto a sheet of pink blotting paper . This rough sketch (now in the Victoria and Albert Museum ) incorporated all
1166-490: A major gamble for Paxton, but circumstances were in his favour: he enjoyed a stellar reputation as a garden designer and builder, he was confident that his design was perfectly suited to the brief, and the commission was under pressure to choose a design and get it built, with the exhibition opening less than a year away. In the event, Paxton's design fulfilled and surpassed all the requirements, and it proved to be vastly faster and cheaper to build than any other form of building of

Queen Victoria mentioned this problem to the Duke of Wellington , who offered the solution, " Sparrowhawks , Ma'am". Paxton was acclaimed worldwide for his achievement and was knighted by Queen Victoria in recognition of his work. The project was engineered by William Cubitt ; Paxton's construction partner
1696-438: A property named Penge Place, which had been excised from Penge Common at the top of Sydenham Hill . The reconstruction of the Crystal Palace began on Sydenham Hill in 1852. The new building, while incorporating most of the constructional parts of the original one at Hyde Park, was so completely different in form as to be properly considered a quite different structure – a ' Beaux-arts ' form in glass and metal. The main gallery
1802-544: A reaping machine that was sent from the United States. Admission prices to the Crystal Palace varied according to the date of visit, with ticket prices decreasing as the parliamentary season drew to an end and London traditionally emptied of wealthy individuals. Prices varied from two guineas (£200 in 2015) (three guineas for a man) for a season ticket, or £1 per day (for the first two days only), then reducing to five shillings per day (until 22 May). The admission price
1908-520: A reasonable number of bays had been completed, the columns for the upper floor were erected (longer shear-legs were used for this, but the operation was essentially the same as for the ground floor). Once the ground floor structure was complete, the final assembly of the upper floor followed rapidly. For the glazing, Paxton used larger versions of machines he had originally devised for the Great Stove at Chatsworth, installing on-site production line systems, powered by steam engines, that dressed and finished
2014-414: A self-supporting shell standing on slim iron columns, with no internal structural walls whatsoever. Because it was covered almost entirely in glass, it also needed no artificial lighting during the day, thereby reducing the exhibition's running costs. Full-size elm trees growing in the park were enclosed within the central exhibition hall near the 27-foot (8 m) tall Crystal Fountain. However this caused
2120-540: A standby design of its own, for a brick building in the rundbogenstil (round-arch style) by Donaldson, featuring a sheet-iron dome designed by Tunnel, but it was widely criticized and ridiculed when it was published in the newspapers. Adding to the committee's woes, the site for the exhibition was still not confirmed. The preferred site was in Hyde Park, adjacent to Princes Gate near Pennington Road, but other sites considered included Wormwood Scrubs , Battersea Park ,

Other structures such as oil rigs, space satellites, aircraft, and ships may also be designed by a structural engineer. Most structural engineers are employed in the construction industry, however, there are also structural engineers in the aerospace, automobile, and shipbuilding industries. In the construction industry, they work closely with architects , civil engineers , mechanical engineers , electrical engineers , quantity surveyors , and construction managers . Structural engineers ensure that buildings and bridges are built to be strong enough and stable enough to resist all appropriate structural loads (e.g., gravity, wind, snow, rain, seismic ( earthquake ), earth pressure, temperature, and traffic) to prevent or reduce

The most outspoken critic was Charles Sibthorp ; he denounced the exhibition as "one of the greatest humbugs, frauds and absurdities ever known," and his trenchant opposition to both the exhibition and its building continued even after it had closed. At this point, renowned gardener Joseph Paxton became interested in

Turner was furious at the rejection and reportedly badgered the commissioners for months afterwards, seeking compensation, but at an estimated £300,000, his design (like Horeau's) was too expensive. As a last resort, the committee came up with

The salary of structural engineers varies from sector to sector within the construction and built environment industry worldwide, depending on the project. For example, structural engineers working in public sector projects earn on average £37,083 per annum compared to the £43,947 average earned by those in commercial projects. Certain regions also represent higher average salaries, with structural engineers in

The British exhibits at the Great Exhibition "held the lead in almost every field where strength, durability, utility and quality were concerned, whether in iron and steel, machinery or textiles." Britain also sought to provide the world with the hope of
3922-447: The Great Exhibition was intended to celebrate. The geometry of the Crystal Palace was a classic example of the concept of form following manufacturer's limitations: the shape and size of the whole building was directly based around the size of the panes of glass made by the supplier, Chance Brothers of Smethwick . These were the largest available at the time, measuring 10 inches (25 cm) wide by 49 inches (120 cm) long. Because

Some have called for a master's degree to be the minimum standard for professional licensing as a civil engineer. There are separate structural engineering undergraduate degrees at the University of California, San Diego and the University of Architecture, Civil Engineering, and Geodesy , Sofia, Bulgaria. Many students who later become structural engineers major in civil, mechanical, or aerospace engineering degree programs, with an emphasis on structural engineering. Architectural engineering programs do offer structural emphases and are often in combined academic departments with civil engineering. In many countries, structural engineering

As soon as two adjacent columns had been erected, a girder was hoisted into place between them and bolted onto the connectors. The columns were erected in opposite pairs, then two more girders were connected to form a self-supporting square—this was the basic frame of each module. The shears would then be moved along and an adjoining bay constructed. When

These included a machine that mechanically grooved the wooden window sash bars and a painting machine that automatically dipped the parts in paint and then passed them through a series of rotating brushes to remove the excess. The last major components to be put into place were the 16 semi-circular ribs of the vaulted transept, which were the only major structural parts that were made of wood. These were raised into position as eight pairs, and all were fixed into place within

It is often suggested that the euphemism " spending a penny " originated at the exhibition, but the phrase is more likely to date from the 1890s when public lavatories, fitted with penny-coin-operated locks, were first established by British local authorities. The Great Exhibition closed on 15 October 1851. The life of the Great Exhibition
5936-518: The exhibition, the Palace was relocated to an open area of South London known as Penge Place which had been excised from Penge Common . It was rebuilt at the top of Penge Peak next to Sydenham Hill , an affluent suburb of large villas. It stood there from June 1854 until its destruction by fire in November 1936. The nearby residential area was renamed Crystal Palace after the landmark. This included

In modern times, the Great Exhibition is a symbol of the Victorian Age , and its thick catalogue, illustrated with steel engravings, is a primary source for High Victorian design. A memorial to the exhibition, crowned with a statue of Prince Albert , is located behind the Royal Albert Hall . It is inscribed with statistics from the exhibition, including the number of visitors and exhibitors (British and foreign), and

The other part of the solution was Paxton's ingenious ventilation system. Each of the modules that formed the outer walls of the building was fitted with a prefabricated set of louvres that could be opened and closed using a gear mechanism, allowing hot stale air to escape. The flooring consisted of boards 22 centimetres (8.7 in) wide which were spaced about 1 centimetre (0.39 in) apart; together with

Human comfort is an issue that is regularly considered limited. Fatigue is also an important consideration for bridges and aircraft design or for other structures that experience many stress cycles over their lifetimes. Consideration is also given to the durability of materials against possible deterioration which may impair performance over
7102-427: The louvres, this formed an effective passive air-conditioning system. Because of the pressure differential, the hot air escaping from the louvres generated a constant airflow that drew cooler air up through the gaps in the floor. The floor too had a dual function: the gaps between the boards acted as a grating that allowed dust and small pieces of refuse to fall or be swept through them onto the ground beneath, where it

To attract future customers from the working classes, the newly expanding railways offered highly discounted tickets for people to travel from distant parts of the country, and special rates were offered to parties, often led by the local vicar. Those too poor to travel lined up by the rail tracks to watch the long trains of open carriages steaming past. The Great Exhibition of 1851 encouraged
7632-444: The parts could be mass-produced in large numbers, and many parts served multiple functions, further reducing both the number of parts needed and their overall cost. Because of its comparatively low weight, the Crystal Palace required no heavy masonry for supporting walls or foundations. The relatively light concrete footings on which it stood could be left in the ground once the building was removed (they remain in place today just beneath

Then the concrete foundations were poured, and the base plates for the columns were set into them. Once the foundations were in place, the erection of the modules proceeded rapidly. Connector brackets were attached to the top of each column before erection, and these were then hoisted into position. The project took place before

These paper souvenirs were printed lithographic cards which were hand-coloured and held together by cloth to give a three-dimensional view of the event. They offered a miniature view of the Crystal Palace when one viewed the cards through the peep holes on the front cover. Visitors purchased these souvenirs so that they could relive
8056-434: The profit made. A range of medals were produced and awarded to exhibitors, jurists and providers of services. The official descriptive and illustrated catalogue of the event lists exhibitors not only from throughout Britain but also from its "Colonies and Dependencies" and 44 "Foreign States". Numbering 13,000 in total, the exhibits included a Jacquard loom , an envelope machine, kitchen appliances, steel-making displays and
8162-466: The project, and with the enthusiastic backing of commission member Henry Cole , he decided to submit his own design. At this time, Paxton was chiefly known for his celebrated career as the head gardener for the Duke of Devonshire at Chatsworth House . By 1850, Paxton had become a preeminent figure in British horticulture and had also earned great renown as a freelance garden designer; his works included
8268-410: The relatively poor quality of the sealant materials available at that time meant that the problem was never totally overcome. To maintain a comfortable temperature inside such a large glass building was another major challenge, because the Great Exhibition took place decades before the introduction of electricity and air-conditioning. Glasshouses rely on the fact that they accumulate and retain heat from
8374-401: The roof of the original Hyde Park structure had a horizontal profile, so heavy rain posed a potentially serious safety hazard. Because normal cast glass is brittle and has low tensile strength, there was a risk that the weight of any excess water build-up on the roof might have caused panes to shatter, showering shards of glass onto the patrons, ruining the valuable exhibits beneath, and weakening
8480-443: The roofing. Once completed, the channels acted both as the joists that supported the roof sections, and as guttering—a patented design now widely known as a " Paxton gutter ". These gutters conducted the rainwater to the ends of each furrow, where they emptied into the larger main gutters, which were set at right angles to the smaller gutters, along the top of the main horizontal roof beams. These main gutters drained at either end into
8586-477: The short time remaining before the exhibition opening, which had already been scheduled for 1 May 1851. Within three weeks, the committee had received some 245 entries, including 38 international submissions from Australia, the Netherlands, Belgium, Hanover , Switzerland, Brunswick , Hamburg and France . Two designs, both in iron and glass, were singled out for praise—one by Richard Turner , co-designer of
8692-412: The situation varies from state to state. Some states have a separate license for structural engineers who are required to design special or high-risk structures such as schools, hospitals, or skyscrapers. In the United Kingdom, most structural engineers in the building industry are members of the Institution of Structural Engineers or the Institution of Civil Engineers . Typical structures designed by
8798-415: The structure. Paxton's ridge-and-furrow roof was designed to shed water very effectively. Rain ran off the angled glass roof panes into U-shaped timber channels which ran the length of each roof section at the bottom of the 'furrow'. These channels were ingeniously multifunctional. During construction, they served as the rails that supported and guided the trolleys on which the glaziers sat as they installed
8904-413: The subject. Professional Engineers bear legal responsibility for their work to ensure the safety and performance of their structures and only practice within the scope of their expertise. In the United States, persons practicing structural engineering must be licensed in each state in which they practice. Licensure to practice as a structural engineer usually be obtained by the same qualifications as for
9010-439: The sun, but such heat buildup would have been a major problem for the exhibition. This would have been exacerbated by the heat produced by the thousands of people who would be in the building at any given time. Paxton solved this with two clever strategies. One was to install external canvas shade-cloths that were stretched across the roof ridges. These served multiple functions: they reduced heat transmission, moderated and softened
9116-463: The surface of the site). The modules could be erected as quickly as the parts could reach the site—some sections were standing within eighteen hours of leaving the factory—and since each unit was self-supporting, workers were able to assemble much of the building section-by-section, without having to wait for other parts to be finished. Fox, Henderson and Co took possession of the site in July 1850, and erected wooden hoardings which were constructed using
9222-481: The surrounding grounds, and two large transepts were added at either end of the main gallery. It was modified and enlarged so much that it extended beyond the boundary of Penge Place, which was also the boundary between Surrey and Kent . The reconstruction was recorded for posterity by Philip Henry Delamotte , and his photographs were widely disseminated in his published works. The Crystal Palace Company also commissioned Negretti and Zambra to produce stereographs of
9328-406: The timber that later became the floorboards of the finished building. More than 5,000 navvies worked on the building during its construction, with up to 2,000 on site at one time during the peak building phase. More than 1,000 iron columns supported 2,224 trellis girders and 30 miles of guttering, comprising 4,000 tons of iron in all. Firstly stakes were driven into the ground to roughly mark out
9434-495: The title of Chartered Structural Engineer . The overall process to become chartered begins after graduation from a UK MEng degree, or a BEng with an MSc degree. To qualify as a chartered structural engineer, a graduate needs to go through four years of Initial Professional Development followed by a professional review interview. After passing the interview, the candidate sits an eight-hour professional review examination. The election to chartered membership (MIStructE) depends on
9540-594: The year of re-opening, 18 handbooks were published in the Crystal Palace Library by Bradbury and Evans as guides to the new installations. Many of these were written by the specialists involved in creating and curating the new displays. So the 1854 guide to the Egyptian Court, destroyed in the 1866 fire, was entitled: 'The Egyptian Court in the Crystal Palace. Described by Owen Jones, architect, and Joseph Bonomi , sculptor'. That which included
9646-464: Was 135 feet (41 m) high, with 772,784 square feet (71,794.0 m ) on the ground floor alone. The Great Exhibition was opened on 1 May 1851 by Queen Victoria. It was the first of the World's fair exhibitions of culture and industry. There were some 100,000 objects, displayed along more than ten miles, by over 15,000 contributors. Britain occupied half the display space inside with exhibits from
9752-452: Was 4 feet (1.2 m) long. By mirroring this triangle he obtained the 8-foot-wide (2.4 m) gables that formed the vertical faces at either end of the prism, each of which was 24 feet (7.3 m) long. With this arrangement, Paxton could glaze the entire roof surface with identical panes that did not need to be trimmed. Paxton placed three of these 8 feet (2.4 m) by 24 feet (7.3 m) roof units side-by-side, horizontally supported by
9858-460: Was able to design and build the largest glass structure yet created, from scratch, in less than a year, and complete it on schedule and on budget. He was even able to alter the design shortly before building began, adding a high, barrel-vaulted transept across the centre of the building, at 90 degrees to the main gallery, under which he was able to safely enclose several large elm trees that would otherwise have had to be felled—thereby also resolving
9964-478: Was collected daily by a team of cleaning boys. Paxton also designed machines to sweep the floors at the end of each day. But in practice, it was found that the trailing skirts of the female visitors did the job well. Thanks to the considerable economies of scale Paxton was able to exploit, the manufacture and assembly of the building parts was exceedingly quick and cheap. Each module was identical, fully prefabricated, self-supporting, and fast and easy to erect. All of
10070-489: Was constructed from cast iron -frame components and glass made almost exclusively in Birmingham and Smethwick . From the interior, the building's large size was emphasized with trees and statues; this served, not only to add beauty to the spectacle, but also to demonstrate man's triumph over nature. The Crystal Palace was an enormous success, considered an architectural marvel, but also an engineering triumph that showed
10176-476: Was for Britain to make "clear to the world its role as industrial leader". Prince Albert, Queen Victoria's consort, was an enthusiastic promoter of the self-financing exhibition; the government was persuaded to form the Royal Commission for the Exhibition of 1851 to establish the viability of hosting such an exhibition. Queen Victoria visited three times with her family, and 34 times on her own. Although
10282-480: Was invited to take the lily to Chatsworth. It thrived under his care, and in 1849 he caused a sensation in the horticultural world when he succeeded in producing the first amazonica flowers to be grown in England. His daughter Alice was drawn for the newspapers, standing on one of the leaves. The lily and its house led directly to Paxton's design for the Crystal Palace. He later cited the huge ribbed floating leaves as
10388-430: Was known as the Crystal Palace pneumatic railway . Dozens of experts such as Matthew Digby Wyatt and Owen Jones were hired to create a series of courts that provided a narrative of the history of fine art. Amongst these were Augustus Pugin 's Mediaeval Court from the Great Exhibition, as well as courts illustrating Egyptian , Alhambra , Roman , Renaissance , Pompeian , and Grecian art and many others. During
10494-480: Was left open. Paxton also used longer trellis girders to create a clear span for the roof of the immense central gallery, which was 72 feet (22 m) wide and 1,800 feet (550 m) long. Paxton's roofing system incorporated his elegant solution to the problem of draining the building's vast roof area. Like the Chatsworth Lily House (but different to its later incarnation at Sydenham Hill), most of
10600-471: Was limited to six months, after which something had to be decided on the future of the Crystal Palace building. Against the wishes of parliamentary opponents, a consortium of eight businessmen, including Samuel Laing and Leo Schuster , who were both board members of the London, Brighton and South Coast Railway (LB&SCR), formed a holding company and proposed that the edifice be taken down and relocated to
10706-516: Was originally erected in Hyde Park in London to house the Great Exhibition of 1851, which showcased the products of many countries throughout the world. The commission in charge of mounting the Great Exhibition was established in January 1850, and it was decided at the outset that the entire project would be funded by public subscription. An executive building committee was quickly formed to oversee
10812-405: Was redesigned and covered with a barrel-vaulted roof; the central transept was greatly enlarged and made even higher; the large arch of the main entrance was framed by a new facade and served by an imposing set of terraces and stairways. The building measured 1,608 feet (490 m) feet in length by 384 feet (117 m) feet across the transepts. The new building was elevated several metres above
10918-411: Was the first major application of his ridge-and-furrow roof design and was at the time the largest glass building in the world, covering around 28,000 square feet (2,600 m ). A decade later, taking advantage of the availability of the new cast plate glass , Paxton further developed his techniques with the Chatsworth Lily House, which featured a flat-roof version of the ridge-and-furrow glazing, and
11024-585: Was the ironwork contractor Fox and Henderson, whose director Charles Fox was also knighted for his contribution. The 900,000 square feet (84,000 m ) of glass was provided by the Chance Brothers glassworks in Smethwick. This was the only glassworks capable of fulfilling such a large order; it had to bring in labour from France to fulfil the order in time. The final dimensions were 1,848 feet (563 m) long by 456 feet (139 m) wide. The building
11130-414: Was then further reduced to one shilling (£5 in 2015), per day—except on Fridays, when it was set at two shillings and six pence, and on Saturdays when it remained at five shillings. The one-shilling ticket proved most successful among the industrial classes, with four and a half million shillings (£22,000,000 in 2015) being taken from attendees in this manner. Two thousand five hundred tickets were printed for
11236-526: Was two stories high, with the upper floor stepped in from the boundary. Most of the building had a flat-profile roof, except for the central transept, which was covered by a 72-foot-wide (22 m) barrel-vaulted roof that stood 168 feet (51 m) high at the top of the arch. Both the flat-profile sections and the arched transept roof were constructed using the key element of Paxton's design: his patented ridge-and-furrow roofing system, which had first seen use at Chatsworth. The basic roofing unit, in essence, took
