摘要
在编程计算钢筋混凝土压弯构件二折线回复力模型的基础上 ,用有限元程序 ANSYS模拟了某斜拉桥的动力特性与弹塑性地震反应 ,利用分析结果总结了该桥的抗震性能 ,为同类桥梁的抗震设计提供了参考。
A computer program is compiled with C++ language codes to calculate the two-line hysteresis model of the pier members of a cable-stayed bridge under strong earthquake motion. Then a whole bridge FEM model is established by ANSYS, dynamic character and nonlinear time history analysis are made based on the hysteresis model. Conclusions are made from the result for the seismic behavior of the bridge, and some advice is given for the design of this kind of bridge.
