摘要
墙板在其平面内具有一定的刚度 ,为钢柱提供了侧向约束 ,提高了钢柱的稳定承载能力。利用大型有限元分析程序ANSYS ,对考虑墙板约束的钢柱承载力进行了非线性有限元分析。说明了墙板约束对轴压钢柱承载力及破坏形式的影响 ,并提出了带有墙板的钢柱轴心受压承载力的简化计算模型。
Light wall panel provides a lateral restriction for a steel column,thus improving the stable bearing capacity of the steel column due to the panel's strength in its own plane. A nonlinear FEM analysis of the steel column's bearing capacity, where the light wall panel's restriction is taken into account is conducted using the commercial software ANSYS. It is explained that the effects of the light wall panel's restriction on the bearing capacity of the axially loaded steel column and its failure mode. Finally a simplified model of calculating the bearing capacity is also proposed.
