摘要
对悬索桥的几种计算理论作了简要的介绍并进行了比较，针对悬索桥的非线性问题作了单独的分析．在使用有限元对悬索桥进行空间分析时，考虑悬索桥不同结构部件的不同结构性能而提出采用不同的单元来模拟．另外对求解悬索桥的非线性方程的数值方法作了简要的介绍，最后分析了悬索桥地震响应中地震激励模型的选取方法．
Several calculating methods of suspension bridge are analyzed and compared in this thesis. Nonlinear factor is studied particularly. When using FEM to analyze suspension bridge, different elements are considered to simulate different structure. Numerical mathematical method and how to select seismic wave is also introduced.
