摘要
采用已有的三参数力学模型模拟半刚性连接梁柱节点的弯矩-转角性能.根据小变形叠加原理,推导了半刚接梁单元杆端弯矩的计算公式以及不同情况下连接的转动刚度与弯矩传递系数.在此基础上,通过对钢框架侧移刚度和半刚接梁单元转动刚度的修正,提出了半刚接钢框架内力和层间位移的简化计算方法.算例结果表明:该计算方法可靠,可用于结构的初步设计和最终校核.
The moment-rotation relation of beam-to-column semi-rigid connections was simulated with the three-parameter mechanical fro：tel. The calculation formulas of the end moments, the rotation rigidity and the transmission coefficient of beam elements with semi-rigid connections were presented on the basis of the superposition principle under small deformation. The calculation methods of the internal forces and the story deflection of these frames were proposed by revising its horizontal rigidity and the rotation rigidity of beam elements. Numerical results of calculations showed that the proposed methods were reliable and helpful in the initial design and final check-up of structures.
