| 摘 要： | 由于缺乏计算理论和方法,大多数半刚性节.4按刚性节点进行设计,与实际情况相差很大.结合外套管式节点拟静力试验得到的初始刚度和弯矩-转角曲线,采用有限元分析的方法,将该节点视为弹簧单元,通过通用有限元软件ANSYS建立有限元模型进行时程计算分析,研究节点刚度对多层钢框架结构抗震性能的影响.计算结果表明:采用外套管式节点连...

| Abstract: | Because of the absence of calculation theory and design method for semi-rigid connections,it is still calculated and designed as rigid connections in China,which leads to the significant difference between the calculation result and the real stressed state of the semi-rigid connection.Based on the initial connection stiffness and the moment-rotation angle curve acquired from a quasi-static experiment on out-shell connections(OSC),and taking the semi-rigid OSC as a spring element,a FEM model is set up by ANS... |
