摘要
联合应用力法与逐段刚化法推导出具有半刚性节点性质的弹簧节点梁单元和平面刚架弹簧单元的单元刚度方程.该方法具有物理概念清楚,推导过程简便、巧妙的特点.本文所建立的弹簧节点梁单元和平面刚架弹簧单元可以应用在具有半刚性节点性质的工程结构的承载力分析与计算中.
We deducted the stiffness equation of the beam element with spring joint and the plane frame of spring element with property of semi-rigid joint by using force method and the method of gradual rigidization. The method has the characterics of clear physical concept, simplicity of deduction processes. The beam element with spring joint and the plane frame of spring element were employed to calculating and analyzing bearing capacity in engineering structures with semi-rigid joints.
