Piers provide vertical supports for bridge spans at intermediate points and perform two main functions: transferring superstructure vertical loads to the foundations and resisting horizontal forces acting on the bridge. A bridge design utilizes support elements (columns) and spanning elements (two orthogonal sets of beams) Vertical support is a category of structural systems or elements in architecture and architectural engineering designed to facilitate the vertical dimensions of space and mass, for example. Structural engineering is a fascinating field that revolves around ensuring that buildings, bridges, and other structures remain stable and secure. One of the key components that make this possible is the use of structural supports. The intermediate supports of multi-span bridges are referred to as “piers,” while the end supports are typically referred to as “abutments. In order to be able to analyze a structure, it is first necessary to be clear about the forces that can be resisted, and transfered, at each level of support throughout the structure. The. The selection of a bridge's primary support system is one of the most consequential decisions in civil engineering. The analysis is based on Euler-Bernoulli beam theory.
