T型钢连接仿古建筑钢结构边节点抗震性能
Seismic Performance of Steel Side Joints of T-stub Connectors in Antique Buildings
摘要
Abstract
In order to study the seismic performance of side joints in ancient-style double-beam-column structures,quasi-static tests were carried out on two steel joints connected by split-type unilateral high-strength bolts and T-stub connection between circular steel tube columns and H-shaped steel beams,with different T-stub connections thicknesses.Through the tests,the hysteresis curves,skeleton curves,stiffness degradation,energy dissipation,ductility and other seismic indicators of the joints were obtained.The influence of the thickness of the T-stub connectors on the failure mode,flexural bearing capacity,and rotational stiffness degradation of the double-beam-column joint was analyzed.The ABAQUS software numerical simulation was used to further investigate the influence of flange and web thickness of the T-stub connectors on joint performance.The results show that both joint specimens exhibit spindle-shaped hysteresis curves,with certain pinching phenomena.Due to the increase in the thickness of the T-stub connectors,the initial stiffness of the joints increased by 23.93%.In the parametric analysis,compared with increasing the web thickness of the T-stub connector alone,increasing the flange thickness had a greater influence on the joint.Properly increasing the flange thickness can more effectively improve the strength of the T-stub connectors.Therefore,this type of joint is more suitable for use in earthquakes.关键词
