33-696: Ten Mile River or Tenmile River may refer to: Rivers [ edit ] Ten Mile River (California) , in northern California Ten Mile River (Housatonic River) , in New York and western Connecticut Tenmile River (Maine) , a tributary of the Saco River Ten Mile River (Seekonk River) , in central Massachusetts and Rhode Island Tenmile Wash , in Arizona Other [ edit ] Ten Mile River Boy Scout Camp , overlooking

66-437: A continuous Marine Protected Area (MPA) zone that extends from the upper limit of the estuary out to 5 nautical miles (9.3 km; 5.8 mi). The MPA zone complements the protections for neighboring lands, including MacKerricher State Park and Inglenook Fen-Ten Mile Dunes Natural Preserve. The Ten Mile River has intermittent ocean connectivity, so that the estuary effectively becomes a freshwater lagoon in some years. As

99-475: A framed bay of a structure, they constitute a SPSW system. Whereas most earthquake resistant construction methods are adapted from older systems, SPSW was invented entirely to withstand seismic activity. SPSW behavior is analogous to a vertical plate girder cantilevered from its base. Similar to plate girders, the SPSW system optimizes component performance by taking advantage of the post- buckling behavior of

132-578: A result of these impacts, the river was listed as sediment impaired under section 303(d) of the Clean water Act in 1998. Improved timber harvest practices and regular road maintenance have reduced sedimentation and allowed continued active management for timber harvest in 45% of the Ten Mile River watershed. The Ten Mile River mainstem begins at the confluence of North Fork Ten Mile River and Middle Fork Ten Mile River, flows southwest then northwest to

165-445: A result, seasonal use by anadromous and marine fishes varies significantly from year to year. When the mouth is open, Ten Mile River Estuary serves as a migration corridor for anadromous salmonids and a rearing area for juvenile coastal fishes, including flatfish and surfperch. In summer, juvenile shiner surfperch ( Cymatogaster aggregata ) will flock to the highly productive salt marshes when tidally flooded. This changes in years when

198-406: Is based on the application of seismic damping systems for wooden buildings. The systems, which can be installed inside the walls of most wooden buildings, include strong metal frame , bracing and dampers filled with viscous fluid. The proposed system is composed of core walls, hat beams incorporated into the top-level, outer columns, and viscous dampers vertically installed between the tips of

231-684: The Earthquake Engineering Research Institute , precast panel buildings had good durability during the earthquake in Armenia, compared to precast frame-panels. One Japanese construction company has developed a six-foot cubical shelter, presented as an alternative to earthquake-proofing an entire building. Concurrent shake-table testing of two or more building models is a vivid, persuasive and effective way to validate earthquake engineering solutions experimentally. Thus, two wooden houses built before adoption of

264-595: The Pacific Ocean . The watershed drains approximately 120 square miles (310 km ) and is neighbored to the south by the Noyo River watershed and to the east and north by the South Fork Eel River watershed. River flow is precipitation-driven. Annual rainfall averages 40 inches (1,000 mm) on the coast and 51 inches (1,300 mm) inland. Under low flow conditions, sand bars constrict

297-642: The 1954 bridge was insufficiently earthquake-safe , a new concrete box girder bridge on Highway 1 was constructed in 2009. The new bridge is 45 feet (14 m) wide and 1,479 feet (451 m) long; it cost $ 43.5 million to construct. In 2012, the Ten Mile River Estuary was designated as a State Marine Conservation Area (SMCA) under the Marine Life Protection Act . At the same time, Ten Mile Beach SMCA and Ten Mile State State Marine Reserve were established, creating

330-565: The 1981 Japanese Building Code were moved to E-Defense for testing. One house was reinforced to enhance its seismic resistance, while the other one was not. These two models were set on E-Defense platform and tested simultaneously. Designed by architect Merrill W. Baird of Glendale, working in collaboration with A. C. Martin Architects of Los Angeles, the Municipal Services Building at 633 East Broadway, Glendale

396-458: The Municipal Services Building of the City of Glendale, California was seismically retrofitted using an innovative combined vibration control solution: the existing elevated building foundation of the building was put on high damping rubber bearings . A steel plate shear wall (SPSW) consists of steel infill plates bounded by a column-beam system. When such infill plates occupy each level within

429-476: The Pacific Ocean 5.7 miles (9.2 km) south of Westport. The North Fork Ten Mile River begins at elevation 2,400 feet (732 m). The Middle Fork Ten Mile River begins at elevation 2,460 feet (750 m) on the north side of Sherwood Peak. The middle and north forks of the river are each 15 miles (24 km) long, and the river extends 7 miles (11 km) longer from their confluence to its mouth at

462-455: The Ten Mile River watershed." The spawning population of coho salmon in Ten Mile River has been observed to decrease from an estimate of 6000 fish in the early 1960s to much lower numbers ranging from 14 to 250 in the 1990s. Contributing factors to this decline include natural variability, excessive sedimentation from logging, increased water temperatures due to the removal of riparian vegetation, and reduced woody debris in salmon habitats. As

495-535: The U.S. National Science Foundation Network for Earthquake Engineering Simulation (NEES) Program. "NEESWood aims to develop a new seismic design philosophy that will provide the necessary mechanisms to safely increase the height of wood-frame structures in active seismic zones of the United States, as well as mitigate earthquake damage to low-rise wood-frame structures," said Rosowsky, Department of Civil Engineering at Texas A&M University . This philosophy

528-403: The area. A United States Environmental Protection Agency study reported that "Sediment was determined to be impacting the cold water fishery, a beneficial use of the Ten Mile River watershed, including the migration, spawning, reproduction, and early development of cold water fish such as coho salmon and steelhead trout. Cold freshwater and estuarine habitats are also designated beneficial uses of

561-449: The crossing a little dangerous on account of the tide, which sometimes renders it impassable for several hours, except by swimming. With some plunging, spurring, and kicking, the opposite side was gained in due time". Later, the river was spanned near its mouth by a bridge on California State Route 1 , north of the community of Inglenook . A concrete beam bridge replaced an older wooden deck truss bridge in 1954. After studies found that

594-561: The early 1870s. At first, trees were cut using single-bladed axes and dragged by oxen to mills at Fort Bragg , 10 miles (16 km) to the south. Railroad lines were introduced on the South Fork in 1910 and on the other parts of the river in the 1920s. In the 1930s, the railroads were replaced by tractor roads; after the passage of the California Forest Practice Act in 1973, tractor logging on steeper slopes

627-575: The earthquake. A destructive earthquake struck a lone, wooden condominium in Japan . The experiment was webcast live on July 14, 2009, to yield insight on how to make wooden structures stronger and better able to withstand major earthquakes. The Miki shake at the Hyogo Earthquake Engineering Research Center is the capstone experiment of the four-year NEESWood project, which receives its primary support from

660-439: The epicenter of the strongest M w 6.6 July 2007 Chūetsu offshore earthquake . This initiated an extended shutdown for structural inspection which indicated that a greater earthquake-proofing was needed before operation could be resumed. On May 9, 2009, one unit (Unit 7) was restarted, after the seismic upgrades . The test run had to continue for 50 days. The plant had been completely shut down for almost 22 months following

693-449: The estuary are home to rare plant species, while the freshwater and saltwater marshes along the estuary provide critical bird habitat. The area is popular for paddle sports and birding. Historically, the Ten Mile River had an important Coho Salmon population, but it has since been surpassed by Steelhead. The river provides cold freshwater habitat for fish migration and spawning, but is environmentally impacted by logging like many rivers in

726-435: The goal of earthquake engineering is to erect structures that fare better during seismic activity than their conventional counterparts. According to building codes , earthquake-resistant structures are intended to withstand the largest earthquake of a certain probability that is likely to occur at their location. This means the loss of life should be minimized by preventing collapse of the buildings for rare earthquakes while

759-487: The hat beams and the outer columns. During an earthquake, the hat beams and outer columns act as outriggers and reduce the overturning moment in the core, and the installed dampers also reduce the moment and the lateral deflection of the structure. This innovative system can eliminate inner beams and inner columns on each floor, and thereby provide buildings with column-free floor space even in highly seismic regions. The term 'seismic architecture' or 'earthquake architecture'

825-442: The loss of the functionality should be limited for more frequent ones. To combat earthquake destruction, the only method available to ancient architects was to build their landmark structures to last, often by making them excessively stiff and strong . Currently, there are several design philosophies in earthquake engineering, making use of experimental results, computer simulations and observations from past earthquakes to offer

858-743: The more advanced (and expensive) techniques of isolation or control to survive strong shaking with minimal damage. Examples of such applications are the Cathedral of Our Lady of the Angels and the Acropolis Museum . Some of the new trends and/or projects in the field of earthquake engineering structures are presented. Based on studies in New Zealand, relating to 2011 Christchurch earthquakes , precast concrete designed and installed in accordance with modern codes performed well. According to

891-515: The mouth is closed - salinities are reduced, slack tides can persist for hours, and the winter fish community of sculpins and Three-spined Stickleback ( Gasterosteus aculeatus ) continues to dominate through summer. Lagoon conditions are ideal for the endangered Tidewater goby ( Eucyclogobius newberryi ), which prefers slow-moving habitats. The goby is found in the estuary and several miles upstream in areas impounded by California Golden beavers (Castor canadensis subauratus). The dunes surrounding

924-544: The narrow river mouth, often blocking it entirely in summer. When this occurs, the estuarine portion of the Ten Mile River temporarily becomes a freshwater lagoon, where salinity and tidal influence are both reduced. Estuarine conditions return when large storm events re-establish ocean connectivity. Earthquake engineering structures Earthquake-resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes . While no structure can be entirely impervious to earthquake damage,

957-500: The required performance for the seismic threat at the site of interest. These range from appropriately sizing the structure to be strong and ductile enough to survive the shaking with an acceptable damage, to equipping it with base isolation or using structural vibration control technologies to minimize any forces and deformations. While the former is the method typically applied in most earthquake-resistant structures, important facilities, landmarks and cultural heritage buildings use

990-614: The steel infill panels. The Ritz-Carlton/JW Marriott hotel building, a part of the LA Live development in Los Angeles , California, is the first building in Los Angeles that uses an advanced steel plate shear wall system to resist the lateral loads of strong earthquakes and winds. The Kashiwazaki–Kariwa Nuclear Power Plant , the largest nuclear generating station in the world by net electrical power rating, happened to be near

1023-424: Was completed in 1966. Prominently sited at the corner of East Broadway and Glendale Avenue, this civic building serves as a heraldic element of Glendale's civic center. In October 2004 Architectural Resources Group (ARG) was contracted by Nabih Youssef & Associates, Structural Engineers, to provide services regarding a historic resource assessment of the building due to a proposed seismic retrofit. In 2008,

1056-740: Was first introduced in 1985 by Robert Reitherman. The phrase "earthquake architecture" is used to describe a degree of architectural expression of earthquake resistance or implication of architectural configuration, form or style in earthquake resistance. It is also used to describe buildings in which seismic design considerations impacted its architecture. It may be considered a new aesthetic approach in designing structures in seismic prone areas. An article in Scientific American from May 1884, "Buildings that Resist Earthquakes" described early engineering efforts such as Shōsōin . Before building codes were improved, door frames were regarded as

1089-640: Was supplanted by more environmentally friendly practices such as the use of cables. The timber on both sides of the river was logged by the Georgia Pacific Company until 1999, when Georgia-Pacific's holdings in the area were acquired by the Hawthorne Timber Company. Timber in the area is logged on a 60-year rotation. An 1861 story in Harper's Monthly includes a passage recounting the crossing of Ten Mile River: "We found
