用APDL对悬索桥结构进行有限元分析

为实现大跨桥梁体系的结构分析，验证APDL在分析中的高效性，应用ANSYS的APDL建立大跨悬索桥有限元模型．选用合适的求解器，重点分析结构在活载下的响应，同时计算出恒载、风载、温度及基础位移工况下所产生的各控制截面内力及应力分布．计算结果表明，该方法能有效实现悬索桥等复杂结构的内力计算，并满足工程实践要求，方便设计方案更改后的结构重新分析．

Finite element analysis on structure of suspension bridge with APDL

To implement the structural analysis on long-span bridges and prove the efficiency of APDL of ANSYS,a finite element model of a suspension bridge is established with APDL.By using suitable solver,inner forces and stress distribution of controlling sections are obtained under different load cases,including dead load,wind,temperature and foundation displacements.And live loads are put on emphasis.The results indicate that this method is effective in structural analysis on complicated structures and meets the ...
