摘要
采用ANSYS建立矮塔斜拉桥塔梁墩固结区局部有限元模型,对结构安装后的最不利工况进行静力分析。分析了塔梁墩固结区混凝土受力,得到其应力分布情况,并对塔梁墩固结区设计方案进行综合评价。
By using ANSYS,we established the FEM model of the fixation part of pylon-beam-pier of the extradosed cable-stayed bridge and tried to do a static analysis of the most unfavorable working conditions after the structure installation.We analyzed the stress distributions of the fixation part of pier-pylon-beam and obtained the resultof its stress distribution.We comprehensively evaluated the design scheme of the fixation of pylon-beam-pier.
