摘要
浙江淳安南浦大桥跨径大(308m),宽跨比小 (1 /19. 81),该桥的面外刚度小于面内刚度。采用反应谱方法对该桥进行抗震性能的分析,结果表明该桥在地震荷载作用下的结构内力大于车辆荷载作用下的内力。
Chunan Nanpu bridge is located in Zhejian province; its span is 308m and the width to span is 1/19.81, rigidity out of plane is letter than in plane. Response spectrum method has been used to analyze the seismic response behavior of the bridge. The results show that internal forces caused by seismic load are bigger than those caused by automobile loads.
