摘要

对某连续刚构桥进行非一致激励地震响应分析,同时考虑行波效应,并将计算结果与一致激励地震输入作对比。分析表明:考虑非一致激励及行波效应下桥梁关键部位的内力及位移计算结果比一致激励地震输入有明显增加,表明对桥梁进行非一致激励地震响应分析很有必要。
        Considering the traveling wave effect, the seismic response of a continuous rigid-frame bridge under non-uniform excitation is analyzed, and the calculation result is compared with the seismic input under uniform excitation. The analysis shows that the internal force and displacement of the key positions are increased more obviously under non-uniform excitation and traveling wave effect than the seismic input under uniform excitation, which indicates that it is necessary to analyze the seismic response of bridge under non-uniform excitation.
