Vierendeel Bridge
A Vierendeel bridge is a bridge employing a Vierendeel truss, named after Arthur Vierendeel. Such trusses are made up of rectangular rather than triangular frames, as are common in bridges using pin–joints. Because of the lack of diagonal members, Vierendeel trusses employ moment joints to resist substantial bending forces. Owing to a lesser economy of materials and the difficulty of design before the advent of computers, this truss is rarely used in bridges outside Belgium. The form is more commonly employed in building structures where large shear walls or diagonal elements would interfere with the building's aesthetics or functionality. The first such bridge was built in steel at Avelgem, Belgium in 1902, following development of the truss form and a method to calculate its strength in 1896 by Arthur Vierendeel. There are many more examples in Belgium, including some built in concrete, mostly designed by Vierendeel's many students from his long career as professor in c ...

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Trusses
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

Bridges In Belgium
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kap Shui Mun Bridge
The Kap Shui Mun Bridge (KSMB) in Hong Kong, part of Lantau Link of Route 8, is one of the longest cable-stayed bridges in the world that transports both road and railway traffic, with the upper deck used for motor vehicles and the lower deck used for both vehicles and the MTR. It has a main span of and an overall length of . It spans the Kap Shui Mun marine channel between Ma Wan and Lantau and has a vertical clearance of above sea level. The bridge was completed in 1997. Structural information The total length of the Kap Shui Mun Bridge includes a approach span on the Lantau side. There is a column in each of the back spans of the cable stayed bridge, making four spans, adding to the main span. This makes the total length . The Ma Wan Viaduct was constructed under the same contract as the KSMB. The viaduct connects the KSMB to the Tsing Ma Bridge, forming the Lantau Link, which was built to provide access to the new airport. The navigation clearance of is part ...

Verdugo Wash
Verdugo Wash is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 16, 2011 tributary of the Los Angeles River, in the Glendale area of Los Angeles County, California. The stream begins just south of Interstate 210 in the Crescenta Valley. It flows southeast along the eastern edge of the Verdugo Mountains, then south through a pass between those mountains and the San Rafael Hills, and finally west to ultimately join the Los Angeles River just northeast of Griffith Park. Its entire path is located within the city of Glendale. With the exception of the free-flowing stream inside the Verdugo Wash Debris Basin Dam, Verdugo Wash is entirely encased in a concrete flood control channel.

Glenoaks Boulevard
Glenoaks Boulevard is a major thoroughfare in Los Angeles County, which stretches some 22.4 miles as a north-south thoroughfare in Sylmar at its intersection with Foothill Boulevard to a west-east thoroughfare in Glendale before ending in the Scholl Canyon area as a minor street. It passes through much of the San Fernando Valley including San Fernando, Pacoima, and Sun Valley. It is also a north-south thoroughfare in Burbank. Glenoaks Boulevard runs east of and parallel to Interstate 5 (Golden State Freeway) in San Fernando and Burbank, and north of and parallel to State Route 134 (Ventura Freeway) in Glendale. The median of Glenoaks Boulevard formerly carried Pacific Electric Railway trains from Brand Boulevard in Glendale to Eton Drive in Burbank. This Glendale–Burbank Line was cut back to Cypress Avenue in 1940 and replaced by buses in 1955. Natural disasters In November 1933 a fire struck the San Gabriel Mountains above La Crescenta, burnt down the trees and weake ...

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances i ...
