基于大变形需求的胶合木梁柱螺栓-钢填板节点抗震性能试验研究
Experimental study on seismic performance of bolted glulam beam-to-column connections with steel plates based on large deformation requirements
摘要
Abstract
To solve the insufficient rotational capacity of bolted glulam beam-to-column connections with steel plates in the large deformation,three improvement methods including applying self-tapping screws,supplemental bolts,and hold-downs to conventional connections were proposed.The cyclic loading tests were performed on eight connection specimens.The failure modes and hysteretic performance were studied based on the test results,and the effects of various methods were compared and analyzed.The results indicate that compared with the conventional connections,the rotational capacity of the connections with supplemental bolts enhances significantly since its bending capacity and maximum rotational angle increase by 53％and 60％,respectively.The rotational capacity of the connections with self-tapping screws and supplemental hold-downs improves limitedly,but their ductility increases up to 48％and 59％,respectively,compared with the conventional ones.All the three methods can effectively improve the energy dissipation capacity,and the cumulative energy dissipation of connections with supplemental bolts during the large deformation and failure phases is remarkable,which is 5.62 times that of the conventional connections.关键词
