Strength Analysis of TSCB Pedestrian Bridges Based on Tsai-Wu Failure Criteria.

The rapid development of FRP ( Filler 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 fail-ure damage of the FRP composite material. The vertical largest deflection was simulated and studied un-der maximum pedestrian load. The strength and deformation analysis provides safety reference for the de-sign of TSCB pedestrian bridges
