不同构造特征的H形钢梁-柱半刚性连接节点抗震性能试验研究及有限元分析
Experimental study and finite element analysis of seismic performance of extended end plate semi-rigid connection with different details
摘要
Abstract
Based on quasi-static tests and finite element analysis of six specimens of H-type steel beam to column extended end plate semi-rigid connections with different details and geometrical dimension,the hysteretic characteristics curves and M-θ curves of core region of connections were obtained,and the key parameters such as ultimate moment of the connection,initial stiffness,ductility and energy dissipation of the connection were analyzed.The test results show that the ultimate moment and initial stiffness of the flange-end plate connections are much higher than that of web-end plate connections,and the later is poor in ductility.If the weak connection of web to end plate is uesd,stiffening ribs in two direction of the web of column should be set to get better strength and ductility.Settlement of the supporting plate against shearing force on flange plate of column has no evident effect on characteristics of the extended beam to column end plate connection,and the everall ductility of the connection will tend to decrease.关键词
