| 摘 要： | 采用ADerKiureghian等提出的考虑地震运动空间变化特性的多支承运动反应谱方法(MSRS法)的理论模型,研究了地震动空间变化特性对大跨度斜拉桥动力响应的影响.以某一实际的大跨度斜拉桥为例,计算了其在空间变化地震动作用下的动力响应,分析并讨论了计算结果.

| Abstract: | A research has been made on effects on dynamic response of large span cable stayed bridge for spatially varying ground motions. The theory model is based on multi support response spectrum method developed by A.Der Kiureghian, et al, which considers the characteristics of spatially varying ground motions. Dynamic responses of a practical large span cable stayed bridge subjected to multi support seismic excitations are computed as an example, and computing results are also analyzed and discussed. |
