| 摘 要： | 通过将地震动时程首尾相连的方式来模拟桥梁结构接连遭受两次地震作用，并利用ANSYS非线性时程分析程序，通过具体算例，对大跨度斜拉桥分别进行一次和二次地震作用下的弹塑性行时程分析，进而比较大跨度斜拉桥在一次和接连两次地震作用下的响应特点，这对以后实际桥梁的抗震设计具有重要意义。

| Abstract: | The bridge model under two successive earthquakes was bulit by the way of connecting the end-to-end of two seismic waves.ANSYS analysis method was employed.Then the elasto-plastic responses and damages of long-span cable-stayed bridge under one and two successive earthquakes were analyzed and compared based on ANSYS nonlinear temporal analysis procedure.The method proposed is useful for earthquakes-resistant performance investigation in practical bridge structure design. |

| Keywords: | cable-stayed bridge ANSYS nonlinear temporal analysis the effect of two earthquakes |
