When the truck hit the top girder, or girders, this caused the pressure/squeeze system to fail, which made the bridge fold up. The design was outdated; more modern types of truss can better withstand such forces. Pedestrian bridge over Moanalua Freeway Honolulu, Hawaii: United States: 6 October 2012: Concrete Pedestrian Bridge
The bridge rotates slowly laterally, allowing pedestrians to remain on the bridge while it is rotating. [1] The design includes a barrier on the western side to prevent entry, while, on the eastern side, pedestrians can step on and off the bridge while it is in motion. The speed of the bridge opening and closing is 0.15 m (0.16 yd) per second. [3]
The standard also encompasses the structural design of bridge foundations [5] as well as the design and requirements of bridge bearings for both ordinary and moving bridges. [7] [8] In 2010, BS 5400 was superseded by the Structural Eurocodes for the design of new bridges. However, BS 5400 still serves as the foundation for assessment standards ...
A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians. [1] While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk , that enables pedestrians to cross ...
The Rock Island Greenway bridge over Knoxville Avenue is expected to reopen next week after structural repairs and a new coat of paint. Here's why this popular Peoria pedestrian bridge over ...
The narrow section at mid-span gives the bridge profile a slight arch shape making this design particularly useful when large headroom is required. The profile also makes the bridge more architecturally pleasing than a beam bridge. Rigid-frame design may be the most efficient bridge type for spans between 35 and 80 feet (11 and 24 m). [5]
Girder bridges have existed for millennia in a variety of forms depending on resources available. The oldest types of bridges are the beam, arch and swing bridges, and they are still built today. These types of bridges have been built by human beings since ancient times, with the initial design being much simpler than what we utilize today.
A bridge can be categorized by what it is designed to carry, such as trains, pedestrian or road traffic (road bridge), a pipeline (Pipe bridge) or waterway for water transport or barge traffic. An aqueduct is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height.
