为研究装配式半刚性钢框架结构的内力和变形,在各类理想约束杆转角位移方程和固端力计算公式基础上,根据半刚性节点刚度进行修正,得到各种半刚性约束等截面杆的转角位移方程、固端力计算公式、杆端转动刚度和传递系数等,并通过算例对半刚性钢框架结构进行计算,计算结果表明:节点刚度对结构内力和变形有着较大的影响,当半刚性节点刚度和柱线刚度比达到一定数值后,计算结果趋于平稳,说明当半刚性达到一定范围后可按照全刚性进行计算。
In order to study the internal force and deformation of the fabricated semi-rigid steel frame structure, based on the formulas of the angular displacement and the end-force of each ideal restraining rod, the semi-rigid joints were modified according to the stiffness of the semi- Corner displacement equation, end-force calculation formula, rod-end rotation stiffness and transfer coefficient, etc. The calculation results of the semi-rigid steel frame structure show that the joint stiffness has a great influence on the internal force and deformation of the structure. After the rigidity and the stiffness ratio of the semi-rigid joints reach a certain value, the calculated results tend to be stable, which shows that when the semi-rigid rigidity reaches a certain range, it can be calculated according to the full rigidity.
