讨论了斜拉桥的动力分析问题。首先,介绍了斜拉桥多点激励的理论知识,然后,运用时程分析方法对某斜拉桥进行了一致激励和多点激励情况的计算分析,得到了桥梁的强迫反应中最显著的模记和地震过程中桥梁中预计出现最大力的位置。
The dynamic analysis of cable-stayed bridges is discussed. First of all, the theoretical knowledge of multi-point excitation of cable-stayed bridge is introduced. Then, the time-history analysis method is used to calculate and analyze the consistent excitation and multi-point excitation of a cable-stayed bridge. In the process of earthquake and the bridge is expected to appear the most forceful position.
