摘要
钢锚梁受力方式明确,通过分阶段张拉索力,能充分发挥钢材应力性能。采用三维有限元软件建立钢锚梁有限元模型,对其在安装中的不同索力工况进行静力计算,得到其应力情况;分析施工斜拉索过程对钢锚梁应力影响,并对设计方案提供指导。
The bearing pattern of steel anchorage beam is clear,and can fully play the stress performance of steel through the tension cable force by stages.The 3D finite element software is used to establish the finite element model of steel anchorage beam,which carries out the static calculation of the different cable force working conditions in its erection to achieve its stress condition.The article analyzes the influence of construction process of stayed cable on the stress of steel anchorage beam,and provides the guidance for the design scheme.
