摘要
对铸钢空心球节点在不同的轴力和弯矩组合作用下的承载力进行了弹塑性有限元分析,得出了节点的塑性发展过程及极限承载力;并基于冲切面剪应力破坏模式推导了轴力和弯矩共同作用下的铸钢空心球节点承载力计算公式。
The elastic-plastic FEM analysis of bearing capacity of cast steel hollow spherical joints under different load combinations of axial force and moment is performed,the plastic development process and ultimate bearing capacity of cast steel hollow spherical joints under load combinations of axial force and moment are obtained.The bearing capacity formula of cast steel hollow spherical joints under load combinations of axial force and moment is also derived,based on the punching shear failure model.
