摘要
对4种半刚接不同节点形式的蜂窝钢梁-密置复合焊接环式箍筋约束高强混凝土柱的梁柱节点试件进行低周反复加载试验.6个试件的滞回曲线及骨架曲线的分析表明:半刚性连接的梁柱节点具有受力合理、延性好、耗能性能良好等特点;蜂窝钢梁-焊接环式箍筋约束混凝土柱节点宜优先采用螺栓端板连接,设计时容易通过控制端板和螺栓的尺寸、强度、数量的方法保证"强节点"的结构设计思想,从而使得节点和构件的耗能能力都能够得到充分发挥.
Four semi-rigid forms of different formal joints, honeycomb steel-high strength concrete restricted by composite welding ring stirrups joints, were tested under low -cycle reversed loads. The analysis of the hysteretic curves and skeleton curves of the six specimens show that the semi-rigid connection with the beam-column joints has characteristics of reasonable force, good ductility and excellent energy performance. It is easy to realize the design of "strong-joint" by controlling the dimension,strength and quality of the end-plate and bolts. And the joints' capability of energy-dissipation and components can be brought into full play as a result.
