屈曲约束型波形板异形柱-梁连接节点抗震性能研究
Study on Seismic Behavior of Buckling-Restrained Type Prefabricated Corrugated Plate Steel Special-Shaped Column-Beam Joint
为发展波形板钢异形柱的配套梁柱节点,并满足结构震后功能修复和抗倒塌性能的需求,本文提出一种具有可恢复功能屈曲约束型波形板异形柱-梁连接节点。通过有限元软件ABAQUS对3组节点算例进行拟静力分析,研究关键构造参数对节点抗震性能的影响,并提出节点承载力简化计算公式。结果表明,新型节点属于半刚性连接节点,具有良好的耗能能力和延性,可以有效实现塑性铰外移,并能实现震后功能恢复。减少翼缘螺栓数量,节点的屈服荷载和极限荷载分别下降34.3%和39.3%,耗能机制以翼缘盖板摩擦滑移耗能为主,累积耗能减少38.2%。螺栓孔洞形式主要影响节点的极限荷载和耗能能力,建议悬臂梁翼缘采用长圆孔螺栓形式,有利于提升节点的耗能能力。建议翼缘盖板厚度取梁高的1/20~1/16,狗骨削弱率取0.6~0.8,此时节点具备足够承载能力且耗能性能良好。提出的节点屈服荷载计算公式精度较高,可为节点设计提供参考。
To develop beam-column joints with corrugated plate special-shaped column and meet the requirements for earthquake resilience and collapse resistance, this paper proposes a buckling-restrained type earthquake-resilient prefabricated corrugated plate steel special-shaped column-beam joint (BEPCSCJ). By using the finite element software ABAQUS, the pseudo-static analysis of 3 groups of models is carried out to study the influence of key structural parameters on the seismic performance of BEPCSCJs, and a simplified calculation formula for the joint bearing capacity is proposed. The results show that BEPCSCJs belong to semi-rigid connection joints, which have good energy dissipation capacity and ductility, and can effectively transfer plastic hinge and achieve post earthquake functional recovery. Reducing the number of flange bolts results in a 34.3% and 39.3% decrease in the yield load and ultimate load of the joint, and the energy dissipation mechanism is mainly friction and sliding energy dissipation of the flange cover plates (FCPs), with a cumulative energy dissipation reduction of 38.2%. The type of bolt holes mainly affects the ultimate load and energy dissipation capacity of the joint. It is suggested to use long slotted hole bolt form for cantilever beam flange, which is conducive to improving the energy dissipation capacity of the joint. When the thickness of the FCPs ranges from 1/20~1/16 of the beam height, and the dog bone weakening rate ranges of the FCPs from 0.6~0.8, the joint can have sufficient bearing capacity and good energy dissipation. The proposed formula for calculating the yield load of joint has high accuracy and can provide reference for the design of the joint.
