摘要
用变刚度的螺旋弹簧模拟梁柱节点半刚性连接的弯曲特性 ,建立了半刚性连接钢框架梁单元的刚度矩阵。通过分别引入横梁修正线刚度和修正转动刚度 ,将等效代替框架法和无剪力分配法推广应用于无支撑半刚性连接钢框架的结构分析 。
The beam element stiffness matrix of semi-rigidly connected steel frames is derived by using a rotation spring which has variable stiffness to model bending behavior of beam-column semi-rigid connection. And by introducing a modified beam linear stiffness and a modified beam rotation stiffness respectively, the equivalent substitution rigidly connected frame method and the non-shear force distribution method are applied in structural analysis of unbraced steel frame with semi-rigid connections. Those two kinds of calculation methods are relatively simple and easy.
