【摘要】 以吉林省某一连续桥梁为工程背景,通过采用大型有限元程序ANSYS建立桥梁模型进行了弹塑性地震响应分析和评价,通过研究各工况下结构在纵桥向和横桥向所能承受的最大地震荷载等级,实现了对两种桥梁拓宽方式抗震性能的对比分析。更多还原

【Abstract】 With a continuous bridge in Jilin as engineering background,the elastic-plastic seismic response was analyzed and evaluated with the bridge model which was built with large finite element program ANSYS,through studying on the longitudinal and lateral bridge bearing capacity seismic grade of the structure in every engineering situation,the comparison analysis of two bridge widening seismic performance was realized.更多还原
