摘要
研究了多维多点地震激励下大跨斜拉桥的地震反应分析,重点研究了相同和不同支承点的不同分量之间的相干性对桥梁的影响,将MSRS法推广至多维多点地震激励情况,对相干性对结构地震反应的影响进行了参数分析。
The paper researches the earthquake response analysis of the long-span cable-stayed bridge under the multi-dimensional and multi-support earthquake,mainly indicates the influence of coherence among the same and different bearing points with various components on bridges,and points out MSRS method to extend the stimulating situation for multi-dimensional and multi-support earthquake,and has the parameter analysis of the influence of the coherence on the structural earthquake response.
