Hyatt Regency Walkway Collapse
On July 17, 1981, two overhead walkways in the Hyatt Regency Hotel in Kansas City, Missouri collapsed, killing 114 people and injuring 216. Loaded with partygoers, the concrete and glass platforms crashed onto a tea dance in the lobby. The collapse resulted in billions of dollars of insurance claims, legal investigations, and city government reforms. The hotel had been built just a few years before, during a nationwide pattern of fast-tracked large construction with reduced oversight and major failures. Its roof had partially collapsed during construction, and the ill-conceived skywalk design progressively degraded due to a miscommunication loop of corporate neglect and irresponsibility. An investigation concluded that it would have failed even under one-third of the weight it held that night. Convicted of gross negligence, misconduct and unprofessional conduct, the engineering company lost its national affiliation and all engineering licenses in four states, but was acquit ...

Cascading Failure
A cascading failure is a failure in a system of interconnection, interconnected parts in which the failure of one or few parts leads to the failure of other parts, growing progressively as a result of positive feedback. This can occur when a single part fails, increasing the probability that other portions of the system fail. Such a failure may happen in many types of systems, including power transmission, computer networking, finance, transportation systems, organisms, the human body, and ecosystems. Cascading failures may occur when one part of the system fails. When this happens, other parts must then compensate for the failed component. This in turn overloads these nodes, causing them to fail as well, prompting additional nodes to fail one after another. In power transmission Cascading failure is common in power grids when one of the elements fails (completely or partially) and shifts its load to nearby elements in the system. Those nearby elements are then pushed beyond t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Box Girder
A box girder or tubular girder (or box beam) is a girder that forms an enclosed tube with multiple walls, as opposed to an i-beam, - or H-beam. Originally constructed of wrought iron joined by riveting, they are now made of rolled steel, rolled or welded steel, aluminium extrusions or prestressed concrete. Compared to an i-beam, -beam, the advantage of a box girder is that it better resists Torsion (mechanics), torsion. Having multiple vertical Web (other)#Engineering, webs, it can also carry more load than an of equal height (although it will use more material than a taller -beam of equivalent capacity). The distinction in naming between a box girder and a tubular girder is imprecise. Generally the term ''box'' girder is used, especially if it is rectangular in section. Where the girder carries its "content" ''inside'' the "box", such as the Britannia Bridge, it is termed a ''tubular'' girder. ''Tubular'' girder is also used if the girder is round or oval in cross-sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tie Rod
A tie rod or tie bar (also known as a hanger rod if vertical) is a slender structural unit used as a tie and (in most applications) capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in a vehicle. Subtypes and examples of applications * In airplane structures, tie rods are sometimes used in the fuselage or wings. * Tie rods are often used in steel structures, such as bridges, industrial buildings, tanks, towers, and cranes. * Sometimes tie rods are retrofitted to bowing or subsiding masonry walls (brick, block, stone, etc.) to keep them from succumbing to lateral forces. The ends of the rods are secured by anchor plates which may be visible from the outside. * The rebar used in reinforced concrete is not referred to as a "tie rod", but it essentially performs some of the same tension-force-counteracting purposes that tie rods perform. * In automobiles, the ''tie rods'' are part of the steerin ...
