三角形高层框筒结构在水平荷载作用下剪力滞后的有限元分析

Finite element analysis of shear lag of triangular tall framed tube structure under horizontal loads

基于正交各向异性连续化等效模型 ,将高层框筒结构转换成弹性力学平面应力平板组合结构 ,并采用ANSYS有限元分析方法分析高层框筒不同高度的剪力滞后现象。同时 ,对工程简化方法进行了评价 。

This paper transforms tall framed tube structure to composite structure of plane-stress in elastic mechanics base upon orthotropic equivalent continuum model and analyze shear lag of different height of tall framed tube by finite element method.At the same time,simplified method in engineering is evaluated.The result provides reference for engineer and designer.
