摘要
利用SAP2000以昆石高速公路K48+400下行线桥为例,采用在纵向以及横向输入其与竖向耦合的地震动反应谱进行了地震分析。在对程序算得的数据进行比较分析后发现,可以对桥墩纵向墩顶剪力、墩底剪力和弯矩进行简化分析,得到近似的地震反应。
In this paper, SAP2000 is used to calculate the seismic response of Kunshi K48 ＋400 highway viaduct. In analysis, response spectrum is imported in vertical and lateral direction. After the date calculate, simplistic methods are found to calculate vertical shearing forces in the head of the piers, vertical shearing forces and bending moment in the bottom of the piers. So approximate seismic response is obtained by simplistic calculation.
