Constructing Pedestrian FootBridge Types from Rahel
Truss Pedestrian Footbridge
Footbridges are needed where a separate pathway has to be provided for people to cross traffic flows or some physical obstacle, such as a river. The loads they carry are, in relation to highway or railway bridges, quite modest, and in most circumstances a fairly light structure is required. They are, however, frequently required to give a long clear span, and stiffness then becomes an important consideration. The bridges are often very clearly on view to the public and therefore the appearance merits careful attention.
Beam Pedestrian Footbridge
Beam bridges, also known as stringer bridges, are the simplest structural forms for bridge spans supported by an abutment or pier at each end.[1] No moments are transferred throughout the support, hence their structural type is known as simply supported.
Tied-Arch Pedestrian Footbridge
Similar to the cable stayed bridges, the main cables of a suspension bridge can be anchored to the ground or to the deck girder. From: Innovative Bridge Design Handbook, 2016
Arch Pedestrian Footbridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today.
