| 摘 要： | 苏拉马都跨海大桥由于桥址处抗震设防烈度较高,又是跨越马都拉海峡的特大型桥梁,其抗震性能尤为重要。采用两水平的抗震设计方法,从地震输入、地震反应谱分析、阻尼器参数的选取、非线性时程分析、结构的抗震性能验算等方面对苏拉马都跨海大桥的抗震性能进行了研究,结果表明,在2 500年重现期的地震作用下,该桥的主塔以及各基础的抗震性能均满足抗震设防要求。

| Abstract: | The seismic performance of Suramadu Bridge is particularly important because of the bridge across the Madula Strait and the high seismic intensity at the bridge site.In this paper,based on the antiseismic design of Suramadu Bridge,seismic behavior of cable-stayed bridge is investigated by two-level earthquake-resistance method from the seismic input,the analysis of earthquake response spectrum,the selection of the damping parameters,the analysis of nonlinear time history and the checking of structural earth... |
