摘　　要：该文主要针对三种截面的钢框架柱侧移刚度进行数值模拟分析,数值模拟软件采用有限元分析软件ABAQUS。通过模拟试验,说明在相同高度、支座条件、惯性矩、轴压比、支座位移条件下的钢框架柱,由于截面不同,侧移刚度存在一定偏差;在支座位移量不断增加情况下,侧移刚度随支座位移量的增加而减小。Numerical simulation analysis on the lateral stiffness of steel frame columns with three sections was carried out.The numerical simulation software is finite element analysis software ABAQUS.The simulation tests show that the lateral stiffness of steel frame columns with different sections differs despite of the same height,support condition,moment of inertia,axial compression ratio and support displacement condition.In the case of increasing support displacement,the lateral stiffness decreases as the displacement of the support increases.
