摘要
运用有限元分析软件ANSYS对某钢管混凝土下承式拱桥进行地震时程分析,通过改变根键的长度和截面积,分析根键各参数对拱桥跨中、拱顶、墩顶、桩顶等控制部位最大位移的影响.结果表明,在一定范围内,增加根键长度、增大根键截面积均能有效减小拱桥在地震作用下的最大位移.
Abstract
The finite element analysis software ANSYS is used to analyze the seismic time history of a concrete filled steel tube through arch bridge.By changing the length and cross-sectional area of the root,the influence of the root on the maximum displacement of the mid-span,arch roof,pier top and pile top of the arch bridge is analyzed.The results show that within a certain range,increasing the length of the root and increasing the cross-sectional area of the root can effectively reduce the maximum displacement of the arch bridge under earthquake.
