摘要
以上海新建中兴路下匝道工程为工程背景,采用非线性时程分析方法,以SAP2000 15.2.1软件为工具,探讨了E2地震作用下曲率半径和墩高对曲线桥地震反应特性的影响。分别总结了曲率半径变化和墩高变化对结构动力特性、内力响应和位移响应影响的一般性规律。
The paper based on the engineering background of ramp of Zhongxing Road project,the influence of curvature radius and pier height on seismic response characteristics of curved bridges under E2 earthquake is explored by using nonlinear time-history analysis method and SAP2000 15. 2. 1 Software. Summarizing the influence of variation of curvature radius and height of pier on structural dynamic characteristics,internal force response and displacement response.
