摘要
结合平寨特大桥工程实例,运用反应谱法和动力时程分析法对此进行了研究。对反应谱、一致激励、行波输入得出的结果进行比较,研究结果表明,时程分析结果较反应谱更接近实际情况,行波输入时竖向分量的影响较一致激励不利。
It has been studied by the following two methods in the paper： response spectrum method and seismic response analysis in time-histo ry method on the background of Pingzhai bridge. The solution data of response spectrum,synchronous excitation, traveling seismic effect have been compared. Re＇suits show that the solution data of seismic response analysis in time-history method are truer than the solution data of re sponse spectrum method and the effect of vertical exaltation of traveling seismic effect, is more disadvantageous than that of synchronous exaltation.
