型钢连接节点抗震性能研究

By finite element ANSYS program,it has been done that the inite element simulation analysis under low-cycle repeating horizonral load.The seismic performance and failure modes and hysteresis curves of different T-jiont flange thickness have been studied. The results of analysis show that:T-jiont is the typical semi-rigid connection;The shapes of hysteresis curve are stable and full,T-jiont has perfect seismic performance;The thickness of T-jiont’s flange has great influence on the seismic performance, its reasonable thickness is 1 ~ 1.5 times the thickness of column flange; when the thickness of T-jiont’s flange is large, it is recommended to increase oblique stiffening ribs in the the domain of column in order to change the damage caused by the too large deformation of column.
