摘要

采用人工生成的地震波,考虑多点激励、行波效应以及结构的几何非线性因素的影响,对混凝土自锚式悬索桥在纵向地震波输入下进行了地震响应研究.分析比较了多点线性一致激励、多点非线性一致激励以及多点非一致激励下主梁、主塔、边墩等控制截面的内力和位移响应时程结果,并对其影响规律进行详细讨论.由于时域分析采用精细逐步积分格式,使计算结果更加精确.
By taking into account the multiple support excitation,traveling wave effect and the nonlinearity of the structure,the artificial seismic waves are utilized to study the seismic response of concrete self-anchored suspension bridge subjected to longitudinal seismic excitation.On the case of multiple support linear uniform,nonlinear uniform and non uniform excitation,the response time histories of internal force and displacement of controlling section of main beam,tower, side pier,are analyzed in detail.Since the High Precision Direct integration (HPD) method is applied in time domain analysis,more accurate results can be obtained.
