新型全栓接H型钢梁柱节点滞回性能研究

提出一种新型全栓接H型钢梁柱节点。为研究节点的滞回性能，采用立式加载方案对4个不同构造方式的新型和传统全栓接H型钢梁柱节点进行拟静力试验，分析各试件的节点破坏模式、P-Δ滞回曲线、M-θ骨架曲线、承载力及延性性能。结果表明:强轴新型全栓接节点与传统全栓接节点相比，滞回曲线、骨架曲线以及各项力学性能指标基本相同。弱轴新型全栓接节点与传统全栓接节点相比，具有更好的滞回性能、更高的延性和更强的承载力，其屈服承载力、极限承载力及延性分别增加了38%、35%和32%。

Hysteretic behavior of new fully bolted H-shaped steel beam-to-column joints

This paper presents a new type of fully bolted H-shaped steel beam-to-column joint.In order to study the hysteretic behavior of the joints,a quasi-static test on four types of new and traditional fully bolted H-shaped beam-to-column joints with different construction methods was carried out.The failure mode of the joint,P-Δ hysteresis curve,M-θ skeleton curve,bearing capacity and ductility were analyzed.The results showed that the hysteresis curve,skeleton curve and mechanical properties of the new fully bolted joints about the strong axis are almost the same as the traditional fully bolted joints.For the behavior about the weak axis,the new fully bolted joints have better hysteretic behavior,higher ductility and stronger bearing capacity than the traditional ones.The yielding bearing capacity,ultimate bearing capacity and ductility increases by 38%,35% and 32%.
