Abstract

Abstract: The rapid development of FRP (Fiber Reinforced Polymer) technology makes it possible to build new pedestrian bridges for public and industrial use. Pedestrian bridges constructed with FRP have the advantages of rapid installation, light weight, corrosion resistance and convenient maintenance. Strength and deflection simulations were studied by using finite element software ANSYS, based on the Swiss FRP structural TSCB pedestrian bridge. The Tsai-Wu failure criteria was used to determine the failure damage of the FRP composite material. The vertical largest deflection was simulated and studied under maximum pedestrian load. The strength and deformation analysis provides safety reference for the design of TSCB pedestrian bridges.
