The beam bridge, the most basic kind of bridge, consists of horizontal beams supported by vertical piers. Related content. The bridge models are defined parametrically, using terms that are familiar to bridge engineers such as layout lines, spans, bearings, abutments, bents, hinges and post-tensioning. Choose the appropriate analysis mode for the project stage—line beam, grillage, or finite element analysis—all combined with traffic load optimization. They are simple, cheap, and effective. Beam bridges used to be made from wood and were called log bridges.Modern ones are mostly made of steel.Beam bridges … Beam bridges can go through a significant amount of wear-and-tear in their lifetime. Bridges are a common feature of the built environment and one of the key elements of civil engineering. Common depths: 20 in., 36 in., 45 in., 54 in., and 72 in.
