| 摘 要： | 浙江淳安南浦大桥是一座跨径大(308m)、宽跨比小(1/19.81)、中承式钢管混凝土桁式拱桥,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。

| Abstract: | Zhejiang Chun'an Nanpu bridge is a concrete filled steel-tube braced arch bridge. The span is 308 meter long and the width-to-span is smaller, only 119.81. The exterior-side rigidity is smaller than the interior-side rigidity. Applying response spectrum method to analyze earthquake resistant behavior, the author gets the result. It illustrates that internal force of this bridge impacted by earthquake load is more than internal force of this bridge impacted by vehicle load. |
