| 摘 要： | 桥梁抗震防灾研究也可以说是桥梁易损性分析问题,Pushover分析方法具有表达非线性静力分析的特性,而在桥梁抗震分析和计算方面也表现出较好的适应能力,阐述该方法的基本原理,并用桥梁实际震害样本与Pushover分析方法计算结果进行对比,其对比结果表明,用Pushover分析方法计算出的结果比较符合实际震害情况,显然该法对处理一般性桥梁问题是可行和有效的。

| Abstract: | The research on disaster prevention and seismic analysis of bridge belongs to the problems of bridge vulnerability.It's well known that Pushover approach is widely used in the field of nonlinear static problems and characterized by great convenience.Besides,this method is capable of being well applied in seismic analysis and numerical calculation of bridges.In this paper,the whole fundamental theory of the Pushover approach is represented in detail.The calculated resuls by this method are compared with the real samples of earthquake disaster of bridges and the results by theory coincide with the data of real earthquake disasters.Finally,the corresponding conclusion is drawn that Pushover approach is possible and effective to deal with the normal problems of bridge disaster. |
