| 摘 要： | 根据半刚性连接梁单元的转动刚度和传递系数,利用集体分配原理和反弯点法,推导了半刚性连接钢框架的竖向跨间刚度计算公式。实例计算结果表明:在节点连接刚度由刚接变为铰接的过程中,竖向跨间刚度逐渐减小且呈非线性变化;当节点连接为铰接时,竖向跨间刚度为零。文中公式计算结果与sap 2000有限元分析软件的计算结果相近,验证了该计算方法的可靠性。

| Abstract: | This paper features the formula about vertical cross-inter stiffness of semi-rigid steel frame derived using mass distribution principle and anti-bend-point method and according to the rotation stiff- ness and transmission coefficient of beam element with semi-rigid connections. Calculation results show that changes of the stiffness from rigid joint to hinge joint results in a gradual decrease and a nonlinear change in vertical cross-inter stiffness and hinge joint gives zero vertical cross-stiffness. The similar calcu- lation results derived from the formula and sap 2000 finite element analysis software verify the reliability of the calculation method. |
