| 摘 要： | 以BASE试件为基础设计了3个具有不同轴压比的ZY试件并进行了非线性有限元分析,研究表明柱轴压比不能太大,把柱的轴压比控制在0.5以内为佳,在方钢管的底部和底角部存在应力集中现象,对方钢管的底部应加大刚度,柱底角部应加强施焊。

| Abstract: | Basing on BASE,the auther designs three ZY square concrete-filled steel tubular columns and analyses them by nonlinear finite element,by research it showes that the axial load ratio shouldn't be too large and control axial load ratio which is smaller than 0.5.The stress poll will appear in the bottom and corner of column,therefore the stiffness of bottom of column must be enhanced,the corner of column must be welded greatly. |
