钢框架不同型式梁柱半刚性节点滞回性能试验研究

半刚性连接兼有刚性和铰支连接的长处，可增加结构的阻尼，延长周期，减小震幅，从而降低震害．但是目前国内规范对半刚性连接节点还没有具体的规定．通过不同构造形式的角钢连接半刚性节点在反复荷载历程下的破坏试验，对节点约束关系、滞回性能、破坏模式和承载能力的研究及对比分析，得到半刚性连接具有良好的延性，且柱轴力、孔洞、角钢等对连接性能有比较明显的影响。

Experimental investigation of hysteretic behavior of different semi-rigid connections in steel framed beam and pillar

Semi-rigid connection has the advantages of both the rigid connection and hinged joint,which can increase structural damping,lengthen period,and decrease vibrational amplitude,so that alleviate seismic hazard.But,for the time being,there is still no particular specification for semi-rigid connection in national code.In this paper,destruction experiment on different semi-rigid connection made of rolled angle was performed under repetitive loading,through which the constraint relationship of connection,hysteretic behavior,destruction mode,and bearing capacity were investigated and analyzed.Thus,the conclusions were able to be obtained:the semi-rigid has a good damping.It was found in the meantime that the axial force of the column,the position and dimension of holes,and the rigidity of rolled angle have quite,evident influence on the performance of the connection.
