Rebar (short for reinforcing bar ), known when massed as reinforcing steel or steel reinforcement , is a tension device added to concrete to form reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression , but has low tensile strength . Rebar usually consists of steel bars which significantly increase the tensile strength of the structure. Rebar surfaces feature a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage.

It has lower intelligibility with the Eastern South Slavic languages Bulgarian and Macedonian , than with Slovene (Slovene
252-485: A concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes. Other readily available types of rebar are manufactured of stainless steel , and composite bars made of glass fiber , carbon fiber , or basalt fiber . The carbon steel reinforcing bars may also be coated in zinc or an epoxy resin designed to resist the effects of corrosion, especially when used in saltwater environments. Bamboo has been shown to be
336-543: A device to reinforce arches, vaults , and cupolas . 2,500 meters of rebar was used in the 14th-century Château de Vincennes . During the 18th century, rebar was used to form the carcass of the Leaning Tower of Nevyansk in Russia, built on the orders of the industrialist Akinfiy Demidov . The cast iron used for the rebar was of high quality, and there is no corrosion on the bars to this day. The carcass of
420-499: A limited ability to carry tensile loads. When rebar is added they are known as "reinforced masonry". A similar approach (of embedding rebar vertically in designed voids in engineered blocks) is also used in dry-laid landscape walls, at least pinning the lowest course in place into the earth, also employed securing the lowest course and/or deadmen in walls made of engineered concrete or wooden landscape ties. In unusual cases, steel reinforcement may be embedded and partially exposed, as in
504-553: A viable alternative to reinforcing steel in concrete construction. These alternative types tend to be more expensive or may have lesser mechanical properties and are thus more often used in specialty construction where their physical characteristics fulfill a specific performance requirement that carbon steel does not provide. Reinforcing bars in masonry construction have been used since antiquity , with Rome using iron or wooden rods in arch construction. Iron tie rods and anchor plates were later employed across Medieval Europe, as

Media and publishers typically select one alphabet or the other. In general, the alphabets are used interchangeably; except in the legal sphere, where Cyrillic is required, there is no context where one alphabet or another predominates. Although Serbian language authorities have recognized

Standard Serbian is based on the most widespread dialect of Serbo-Croatian, Shtokavian (more specifically on the dialects of Šumadija-Vojvodina and Eastern Herzegovina ), which is also the basis of standard Croatian , Bosnian , and Montenegrin varieties and therefore
756-424: Is also used in high-corrosion environments. It is available in many forms, such as spirals for reinforcing columns, common rods, and meshes. Most commercially available rebar is made from unidirectional fibers set in a thermoset polymer resin and is often referred to as FRP. Some special construction such as research and manufacturing facilities with very sensitive electronics may require the use of reinforcement that
840-424: Is approximated as (bar size/9)² square inches. For example, the area of #8 bar is (8/9)² = 0.79 square inches. Bar sizes larger than #8 follow the 1 ⁄ 8 -inch rule imperfectly and skip sizes #12–13, and #15–17 due to historical convention. In early concrete construction bars of one inch and larger were only available in square sections, and when large format deformed round bars became available around 1957,

Most steel reinforcement is divided into primary and secondary reinforcement: Secondary applications include rebar embedded in masonry walls, which includes both bars placed horizontally in a mortar joint (every fourth or fifth course of block) or vertically (in the horizontal voids of cement blocks and cored bricks, which is then fixed in place with grout . Masonry structures held together with grout have similar properties to concrete – high compressive resistance but

Rajko Mitić Stadium, renamed in December 2014 in honor of the club's former player and legend Rajko Mitić (1922–2008), has a seating capacity of 53,000 and is currently the largest stadium in Serbia by capacity . The stadium has hosted numerous international matches at a senior level, including the European Cup final in 1973 and
1092-522: Is non-conductive to electricity, and medical imaging equipment rooms may require non-magnetic properties to avoid interference. FRP rebar, notably glass fibre types have low electrical conductivity and are non-magnetic which is commonly used for such needs. Stainless steel rebar with low magnetic permeability is available and is sometimes used to avoid magnetic interference issues. Reinforcing steel can also be displaced by impacts such as earthquakes , resulting in structural failure. The prime example of this

The shaking of the earthquake caused rebars to burst from the concrete and buckle . Updated building designs, including more circumferential rebar, can address this type of failure. US/Imperial bar sizes give the diameter in units of 1 ⁄ 8 inch (3.2 mm) for bar sizes #2 through #8, so that #8 = 8 ⁄ 8 inch = 1-inch (25 mm) diameter. There are no fractional bar sizes in this system. The "#" symbol indicates

The sort order of the ćirilica ( ћирилица ) alphabet: The sort order of the latinica ( латиница ) alphabet: Serbian is a highly inflected language , with grammatical morphology for nouns, pronouns and adjectives as well as verbs. Serbian nouns are classified into three declensional types, denoted largely by their nominative case endings as "-a" type, "-i" and "-e" type. Into each of these declensional types may fall nouns of any of three genders : masculine, feminine or neuter. Each noun may be inflected to represent
2520-410: The Latin script predominates, although both scripts are commonly seen. The Serbian government has encouraged increasing the use of Cyrillic in these contexts. Larger signs, especially those put up by the government, will often feature both alphabets; if the sign has English on it, then usually only Cyrillic is used for the Serbian text. A survey from 2014 showed that 47% of the Serbian population favors

These epoxy-coated bars are used in over 70,000 bridge decks in the US, but this technology was slowly being phased out in favor of stainless steel rebar as of 2005 because of its poor performance. Requirements for deformations are found in US-standard product specifications for steel bar reinforcing, such as ASTM A615 and ASTM A706, and dictate lug spacing and height. Fibre-reinforced plastic rebar

Furthermore, Turner warned that Kahn's system could result in a brittle failure as it did not have longitudinal reinforcement in
3864-929: The industry manufactured them to provide the cross-sectional area equivalent of standard square bar sizes that were formerly used. The diameter of the equivalent large format round shape is rounded to the nearest 1 ⁄ 8 inch to provide the bar size. For example, #9 bar has a cross section of 1.00 square inch (6.5 cm ), and therefore a diameter of 1.128 inches (28.7 mm). #10, #11, #14, and #18 sizes correspond to 1 1 ⁄ 8 inch, 1 1 ⁄ 4 , 1 1 ⁄ 2 , and 2-inch square bars, respectively. Sizes smaller than #3 are no longer recognized as standard sizes. These are most commonly manufactured as plain round undeformed rod steel but can be made with deformations. Sizes smaller than #3 are typically referred to as "wire" products and not "bar" and specified by either their nominal diameter or wire gage number. #2 bars are often informally called "pencil rod" as they are about
3948-682: The local guard. As rust takes up greater volume than the steel from which it was formed, it causes severe internal pressure on the surrounding concrete, leading to cracking, spalling , and, ultimately, structural failure . This phenomenon is known as oxide jacking . This is a particular problem where the concrete is exposed to salt water, as in bridges where salt is applied to roadways in winter, or in marine applications. Uncoated, corrosion-resistant low- carbon / chromium (microcomposite), silicon bronze , epoxy -coated, galvanized , or stainless steel rebars may be employed in these situations at greater initial expense, but significantly lower expense over

When US/Imperial sized rebar are used in projects with metric units, the equivalent metric size is typically specified as the nominal diameter rounded to the nearest millimeter. These are not considered standard metric sizes, and thus is often referred to as a soft conversion or the "soft metric" size. The US/Imperial bar size system recognizes the use of true metric bar sizes (No. 10, 12, 16, 20, 25, 28, 32, 36, 40, 50 and 60 specifically) which indicates

This artificial idiom superseded the works of poets and historians like Gavrilo Stefanović Venclović , who wrote in essentially modern Serbian in the 1720s. These vernacular compositions have remained cloistered from the general public and received due attention only with the advent of modern literary historians and writers like Milorad Pavić . In
5712-691: The stadium and the entire sports complex. It included, among other changes, the lowering of the west stand and construction of the VIP section so as the removal of the athletic's track. In 2012, Red Stars executive board signed a memorandum for the reconstruction of the Rajko Mitić Stadium. The current stadium is expected to be redesigned by Chinese company NCEC (Natong Construction Engineering Constructing Co.) in corporation with Portuguese holding company Sonae Sierra . The 34.8 hectares of land, named Zvezdani Grad (English: Star City or Starry City), will include
5796-614: The stadium has hosted the following events: [REDACTED] Media related to Stadion Crvena Zvezda at Wikimedia Commons Serbian language Serbian ( српски / srpski , pronounced [sr̩̂pskiː] ) is the standardized variety of the Serbo-Croatian language mainly used by Serbs . It is the official and national language of Serbia , one of the three official languages of Bosnia and Herzegovina and co-official in Montenegro and Kosovo . It
5880-464: The stadium included YU Rock Misija on 15 June 1985, a show that lasted 8 hours in front of a gathered crowd of 30,000 people though they were not allowed onto the stadium's pitch by the decision of Red Star's management. Serbian folk singer Ceca held a huge concert on 15 June 2002 in front of 70,000 people. Most recently, Aca Lukas played a show at the stadium on 8 June 2013 in front of 50,000 people. In addition to football matches and concerts,
5964-487: The stadium is to be in the form of a five-pointed star. The cost of the project is estimated to be between €450–600 million. In 2023, the club announced that it is evaluating two locations for the new stadium: the current location and a place 300 meters away from the current venue. The club has further clarified that a reconstruction of the existing structure is not a viable option, as it would not enable Crvena Zvezda to achieve its objective of doubling season ticket sales from
6048-610: The stadium saw its largest crowd on 23 April 1975 at the Cup Winners Cup semi-final home leg against the Hungarian side Ferencváros 2–2. There were officially 96,070 spectators in the stands that night with purchased tickets, but it is believed that the stadium was filled to the maximum allowable capacity which at the time was 110,000. In the years since, the stadium's capacity has gradually decreased. Following different modernization touch-ups, more seats were added. During
6132-477: The stadium with approximately 50,000 seats, fitness center, ambulance, shopping and spa center, office towers, a five-star hotel, modern apartment blocks and underground parking. The area between the stadium and the shopping center, which will allow a visit in the summer, and winter conditions, will be used for markets, cafes, restaurants, and provide space for temporary exhibitions and performances. Ticket office and club shop will also be placed in this covered area. On
6216-542: The steel tie bars that constrain and reinforce the masonry of Nevyansk Tower or ancient structures in Rome and the Vatican. Steel has a thermal expansion coefficient nearly equal to that of modern concrete . If this were not so, it would cause problems through additional longitudinal and perpendicular stresses at temperatures different from the temperature of the setting. Although rebar has ribs that bind it mechanically to
6300-466: The still unfinished stands. The very first visitor to the stadium is known to be Laza Petrović, a peasant from the Loznica vicinity. This fiery Red Star fan arrived to the new stadium early in the morning and took his place in the eastern stand. He took out cheese and a bannock from his bag, then ate his breakfast while he waited patiently until the late afternoon for the game to start. The largest crowd
6384-552: The tower was connected to its cast iron tented roof , crowned with one of the first known lightning rods . However, not until the mid-19th century, with the embedding of steel bars into concrete (thus producing modern reinforced concrete ), did rebar display its greatest strengths. Several people in Europe and North America developed reinforced concrete in the 1850s. These include Joseph-Louis Lambot of France, who built reinforced concrete boats in Paris (1854) and Thaddeus Hyatt of
6468-670: The twisting would weaken the iron. In 1889, Ransome worked on the West Coast mainly designing bridges. One of these, the Alvord Lake Bridge in San Francisco's Golden Gate Park, was the first reinforced concrete bridge built in the United States. He used twisted rebar in this structure. At the same time Ransome was inventing twisted steel rebar, C.A.P. Turner was designing his "mushroom system" of reinforced concrete floor slabs with smooth round rods and Julius Kahn
6552-404: Was built which was difficult to maintain. Because of the winds, the holes were left in the iron construction, but the auxiliary premises were built there even though they shouldn't have. Also, the workers' barracks at the auxiliary stadium were used by the club administration until the proper premises were built at the west stand in 1973. Administrative building also has a single room occupancy for
6636-481: Was devised in 1814 by Serbian linguist Vuk Karadžić , who created it based on phonemic principles. The Latin alphabet used for Serbian ( latinica ) was designed by the Croatian linguist Ljudevit Gaj in the 1830s based on the Czech system with a one-to-one grapheme-phoneme correlation between the Cyrillic and Latin orthographies, resulting in a parallel system. Serbian is a standardized variety of Serbo-Croatian ,
6720-560: Was experimenting with an innovative rolled diamond-shaped rebar with flat-plate flanges angled upwards at 45° (patented in 1902). Kahn predicted concrete beams with this reinforcing system would bend like a Warren truss , and also thought of this rebar as shear reinforcement. Kahn's reinforcing system was built in concrete beams, joists, and columns. The system was both praised and criticized by Kahn's engineering contemporaries: Turner voiced strong objections to this system as it could cause catastrophic failure to concrete structures. He rejected
6804-601: Was not nearly enough. The majority of the funding came from the Executive Council, as the Government of Serbia was called at that time, which conditioned the funds with the construction of the athletic lanes. Construction was continued even after the inaugural match in 1963 and the costs amounted. Roof above the west stand was to be very expensive, with concrete arches, but prime minister Slobodan Penezić Krcun refused to grant that much money. Instead, an iron roof
6888-401: Was recorded that autumn at a derby against Partizan Belgrade – 108,000 people. Next year, after the stadium was fully completed its capacity increased to 110,000 spectators and it got the unofficial moniker - Marakana , in honour of the famous Brazilian stadium . Apart from the look, the new stadium also featured a magnificent grass pitch with drainage. The first official goal at the stadium
6972-419: Was scored by Trifun Mihailović in a youth match between Red Star and Jedinstvo from Zemun , a prelude to the first league match with NK Rijeka. The first official top division goal was scored by Nedeljko Vukoje from Rijeka while Dušan Maravić scored Red Star's first ever goal at the stadium, which resulted in a draw in the same game. Still on the subject of records, according to the number of tickets sold,
7056-488: Was to play against CDNA from Bulgaria (today CSKA Sofia ). The municipal inspector from Stari Grad inspected the venue and declared it unusable, for the wooden beams were completely rotten. Until the new stadium was built, Red Star mostly played as the host at the JNA Stadium (today Partizan Stadium ) while using some smaller venues for less important matches. On 27 December 1959, Red Star played its last match at
