Buckling Restrained Brace
A buckling-restrained brace (BRB) is a structural brace in a building, designed to allow the building to withstand cyclical lateral loadings, typically earthquake-induced loading. It consists of a slender steel core, a concrete casing designed to continuously support the core and prevent buckling under axial compression, and an interface region that prevents undesired interactions between the two. Braced frames that use BRBs – known as buckling-restrained braced frames, or BRBFs – have significant advantages over typical braced frames. History The concept of BRBs was developed in Japan by Nippon Steel at the end of the 1980s and was known by its trademark name of Unbonded Brace. It was first installed in the United States in 1999, in the Plant & Environmental Sciences Building in U.C. Davis. In 2002, both CoreBrace LLC and Star Seismic LLC were incorporated, and began competition with Nippon in the BRB design market. BRB usage is currently accepted, with its design regulated in c ...

Buckling
In structural engineering, buckling is the sudden change in shape (deformation) of a structural component under load, such as the bowing of a column under compression or the wrinkling of a plate under shear. If a structure is subjected to a gradually increasing load, when the load reaches a critical level, a member may suddenly change shape and the structure and component is said to have ''buckled''. Euler's critical load and Johnson's parabolic formula are used to determine the buckling stress in slender columns. Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capacity. However, if the deformations that occur after buckling do not cause the complete collapse of that member, the member will continue to support the ...

Levi's Stadium From Air
Levi Strauss & Co. () is an American clothing company known worldwide for its Levi's () brand of denim jeans. It was founded in May 1853 when German-Jewish immigrant Levi Strauss moved from Buttenheim, Bavaria, to San Francisco, California, to open a West Coast branch of his brothers' New York dry goods business. Although the corporation is registered in Delaware, the company's corporate headquarters is located in Levi's Plaza in San Francisco. History Origin and formation (1853–1890s) German-Jewish immigrant Levi Strauss started his trading business at the 90 Sacramento Street address in San Francisco and then moved the location to 62 Sacramento Street. In 1858, the company was listed as ''Strauss, Levi (David Stern & Levis Strauss) importers clothing, etc. 63 & 65 Sacramento St.'' (today, on the current grounds of the 353 Sacramento Street Lobby ) in the San Francisco Directory with Strauss serving as its sales manager and his brother-in-law, David Stern, as its manager.

Earthquake Engineering
Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a major earthquake. Earthquake engineering is the scientific field concerned with protecting society, the natural environment, and the man-made environment from earthquakes by limiting the seismic risk to socio-economically acceptable levels. Traditionally, it has been narrowly defined as the study of the behavior of structures and geo-structures subject to seismic loading; it is considered as a subset of structural engineering, geotechnical engineering, mechanical engineering, chemical engineering, applied physics, etc. However, the tremendous costs experienced in recent earthquakes have led to an ...

Major Soccer League
Major (commandant in certain jurisdictions) is a military rank of commissioned officer status, with corresponding ranks existing in many military forces throughout the world. When used unhyphenated and in conjunction with no other indicators, major is one rank above captain, and one rank below lieutenant colonel. It is considered the most junior of the field officer ranks. Background Majors are typically assigned as specialised executive or operations officers for battalion-sized units of 300 to 1,200 soldiers while in some nations, like Germany, majors are often in command of a company. When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including ''general-major'' or ''major general'', denoting a low-level general officer, and ''sergeant major'', denoting the most senior non-commissioned officer (NCO) of a military unit. The term ''major'' can also be used with a hyphen to denote the leader of a military band such as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Washington Mutual
Washington Mutual (often abbreviated to WaMu) was the United States' largest savings and loan association until its collapse in 2008. A savings bank holding company is defined in United States Code: Title 12: Banks and Banking; Section 1842: Definitions; Subsection (l): Savings Bank Holding Company See: On Thursday, September 25, 2008, the United States Office of Thrift Supervision (OTS) seized Washington Mutual’s banking operations and placed it into receivership with the Federal Deposit Insurance Corporation (FDIC). The OTS took the action due to the withdrawal of $16.7 billion in deposits during a 9-day bank run (amounting to 9% of the deposits it had held on June 30, 2008). The FDIC sold the banking subsidiaries (minus unsecured debt and equity claims) to JPMorgan Chase for $1.9 billion, which had been considering acquiring WaMu as part of a plan internally nicknamed “Project West.” All WaMu branches were rebranded as Chase branches by the end of 2009.

Levi's Stadium
Levi's Stadium is an American football stadium located in Santa Clara, California, just outside San Jose in the San Francisco Bay Area. It has served as the home venue for the National Football League (NFL)'s San Francisco 49ers since 2014. The stadium is located approximately south of San Francisco. It is named after Levi Strauss & Co., which purchased naming rights in 2013. In 2006, the 49ers proposed constructing a new stadium at Candlestick Point in San Francisco, the site of their erstwhile home, Candlestick Park. The project, which included plans for retail space and housing improvements, was claimed to be of great potential benefit to the nearby historically blighted neighborhood of Hunters Point. After negotiations with the city of San Francisco fell through, the 49ers focused their attention on a site adjacent to their administrative offices and training facility in Santa Clara. In June 2010, Santa Clara voters approved a measure authorizing the creation of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seismic Retrofitting
Seismic retrofitting is the modification of existing built environment, structures to make them more resistant to seismology, seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries (US, Japan etc.) and late 1970s for many other parts of the world (Turkey, China etc.), many structures were designed without adequate detailing and reinforcement for seismic protection. In view of the imminent problem, various research work has been carried out. State-of-the-art technical guidelines for seismic assessment, retrofit and rehabilitation have been published around the world – such as the ASCE-SEI 41 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression (physics)
In mechanics, compression is the application of balanced inward ("pushing") forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions.Ferdinand Pierre Beer, Elwood Russell Johnston, John T. DeWolf (1992), "Mechanics of Materials". (Book) McGraw-Hill Professional, It is contrasted with tension or traction, the application of balanced outward ("pulling") forces; and with shearing forces, directed so as to displace layers of the material parallel to each other. The compressive strength of materials and structures is an important engineering consideration. In uniaxial compression, the forces are directed along one direction only, so that they act towards decreasing the object's length along that direction. The compressive forces may also be applied in multiple directions; for example inwards along the edges of a plate or all over the side surface of a cylinder, so as to reduce it ...
