摘要
随着FRP(Fiber Reinforced Polymer)技术的快速发展,给公共和工业用人行桥提供了新型有效的解决方案.FRP建造桥梁结构具有施工速度快、重量轻、耐腐蚀性好、易于维护等优点.本文以瑞士FRP结构TSCB(Twin Shape Composed Beam)人行桥为工程背景,利用有限元分析软件ANSYS对TSCB人行桥桥梁强度及形变进行了有限元仿真分析.对TSCB人行桥在极限行人载荷下的跨中竖向最大挠度进行了仿真,并运用Tsai-Wu失效准则对TSCB人行桥的各层材料进行了强度分析,为TSCB人行桥的安全性提供了设计参考.
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 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 .
