2024年12月23日 · Bridge, structure that spans horizontally between supports, whose function is to carry vertical loads. Generally speaking, bridges can be divided into two categories: standard overpass bridges or unique-design bridges over rivers, chasms, or estuaries. Learn more about the history and design of bridges in this article.

Suspension bridge, bridge with overhead cables supporting its roadway. Modern suspension bridges are light and aesthetically pleasing and can span longer distances than any other bridge form. Learn about the form, mechanics, construction, and history of suspension bridges.

2024年12月23日 · Bridge - Truss Design, Construction, Types: A single-span truss bridge is like a simply supported beam because it carries vertical loads by bending. Bending leads to compression in the top chords (or horizontal members), tension in the bottom chords, and either tension or compression in the vertical and diagonal members, depending on their ...

truss bridge, bridge with its load-bearing structures composed of a series of wooden or metal triangles, known as trusses. Given that a triangle cannot be distorted by stress, a truss gives a stable form capable of supporting considerable external loads over a large span.

bridge, Structure that spans horizontally to allow pedestrians and vehicles to cross a void. The simplest bridge is the beam (or girder) bridge, consisting of straight, rigid beams of wood, steel, or concrete placed across a span. Ancient Roman bridges are famous for their rounded arch form, which permitted spans much longer than those of stone ...

Arch bridge, bridge in which the main supporting elements are arches. Arch bridges can be made of stone, concrete, iron, or steel and typically require less material than a beam bridge of the same span.

A bridge is a structure that allows people and vehicles to cross over an open space. Bridges span, or stretch across, deep pits in the earth, bodies of water, and roads . Types of Bridges

2024年12月23日 · One of the major structures is the Ikuchi cable-stayed bridge, with a main span of 490 metres (1,610 feet). The two towers of the Ikuchi Bridge are delta-shaped, with two inclined planes of fan-arranged stays.

2024年12月23日 · Bridge - Cantilever, Design, Construction: Like suspension bridges, steel cantilever bridges generally carry heavy loads over water, so their construction begins with the sinking of caissons and the erection of towers and anchorages.

2024年12月23日 · Bridge - Live Load, Dead Load, Structural Design: The primary function of a bridge is to carry traffic loads: heavy trucks, cars, and trains. Engineers must estimate the traffic loading.
