Finite Element Analysis Of Skew Girder Type Bridge

Abstract

Bridges from vital links in the communication system. Normally the bridges are straight for simplicity of construction and design, but sometime site condition for bridges is such that it is not possible to have straight bridge. In such case it is necessary to construct the skew or curved bridge. The analysis of straight bridge is relatively easy but the analysis of skew bridge is somewhat difficult. In present paper girder Type Bridge is analyzed for different skew angles varying farm 0" to 20'' by finite element method and grillage analogy method. The variation of shear force and bending moment obtained by both the method are compared. For the analysis of bridge girder finite element based software SAP2000 computer program is used for both the methods.
