方钢管混凝土柱-钢梁隔板贯通节点抗震性能试验
|
摘要
为研究方钢管混凝土柱与钢梁连接的隔板贯通式节点的抗震性能,对4个足尺节点试件进行了低周反复荷载试验,分析了各试件的破坏过程及特征,并对节点的承载力、延性、耗能能力和刚度退化等抗震性能指标进行了深入的研究与分析.结果表明,隔板贯通节点滞回曲线饱满,具有较强的耗能能力;钢梁翼缘与隔板的连接构造对节点的延性、耗能能力和刚度退化影响较大,倒角放坡型节点比侧板加强型节点具有更好的抗震性能;隔板的厚度、浇筑孔径和钢管的宽厚比对梁端破坏节点的抗震性能影响较小,但在试件中浇筑混凝土可以显著提高节点刚度,减小核心区的剪切变形,改善隔板贯通节点的抗震性能.
Four full-scale cruciform specimens were subjected to low-reversed cyclic loading to investigate the seismic performance of diaphragm-through joint between concrete-filled square steel tubular column and steel beam.The failure process and feature of each specimen were described and load-carrying capacity,ductility,energy dissipation,rigidity degeneration were analyzed.Results show that the specimens of diaphragm-through joint have stable hysteretic characteristic and enough energy dissipation capacity.Details of the steel beam flange connecting with the diaphragm have obvious effect on the ductility,energy dissipation and rigidity degeneration,and joints with fillet slopes at the connecting zone are better than those reinforced by taper plate welded to the beam flanges and diaphragm with regard to the seismic performance.Diaphragm thickness,diameter of concrete cast hole and width-to-thickness ratio of the tube have less influence on joint seismic behavior.However,the concrete filled in the tube can greatly increase the joint rigidity,reduce shearing deformation of joint panel zone and enhance the seismic performance of diaphragm-through joint.
