摘要
对独塔双索面斜拉桥门形桥塔进行反应谱分析,分别建立斜拉桥桥塔裸塔有限元模型和在全桥分析中的桥塔有限元模型,并计算两模型在E1地震作用下的内力和位移。比较和分析两种模型的内力和位移的异同及分布规律,以及分析两个模型分别在纵桥向、横桥向及竖向地震作用下的内力和位移分布规律。
Response spectrum analysis of tower of single tower cable-stayed bridge have been taken,and set up the bare tower of cable-stayed bridge finite element model and the tower of cable-stayed bridge in the final stage.Finally,the internal force and the displacement under E1 seismic effect in the longitudinal direction,lateral direction and vertical direction are calculated and analyzed their distribution laws.
