摘要
文章基于非线性有限元分析,对公路桥梁的抗震性能展开优化设计.首先对钢桁梁柔性拱桥建立非线性有限元模型,并对其抗震性能进行了位移响应分析.分析结果显示,在纵向和横向地震组合下,拱肋和主桁的位移均较大,但整体抗震性能良好,且受到横向地震组合的主要控制.
Abstract
Based on the non-linear finite element analysis,this paper conducts optimization design of the seismic performance of highway bridges.Firstly,the non-linear finite element model of steel truss flexible arch bridge is established,and the displacement response analysis of its seismic performance is carried out.The analysis results show that the displacements of the arch rib and the main truss are large under the longitudinal and transverse seismic combinations,but the overall seismic performance is good and is mainly controlled by the transverse seismic combination.
