摘　　要：为了能使半刚性连接结构在设计应用上,尤其是在动力分析方面实现程序化,必须要获得关于半刚性连接的M-θ滞回曲线模型。通过试验的方法,充分研究双腹板、顶底角钢半刚性连接节点的滞回曲线模型,并用改进的双线性模型模拟试件的滞回曲线,最后提出一个改进的恢复力模型并确定出模型的参数。In order to realize routinization of a semi-rigid structure in the design and application process, especially in the dynamic analysis, it is necessary to set up a M-O hysteresis curve model of semi-rigid connections. Using the test methods, an adequate research is carried out on the hysteresis curve model of the semi-rigid connections with dual-web and top and seat angle; an improved two-lane model is used to simulate the hysteresis curve of specimen;finally, an improved model is proposed and the parameters of the model are determined.
