摘要

为研究方钢管混凝土柱与U形钢组合梁分离式内隔板节点的抗震性能，对4个节点试件进行低周反复加载试验，试验参数为内隔板形式和梁柱交界面处有无加强连接。分析各试件的破坏模式、滞回性能、延性、耗能等指标，并给出加劲板的设计建议。结果表明：4个节点试件的破坏模式均为梁端受弯破坏，滞回曲线呈反S形、有明显的捏缩现象；试件的位移延性系数

为2.3~3.1，弹性层间位移角

为1/68~1/53，弹塑性层间位移角

为1/28~1/19，等效黏滞阻尼系数

为0.12~0.16，变形能力较好，并具备一定耗能能力；改变内隔板形式对试件的承载能力影响较小，但相较于传统内隔板节点试件，分离式内隔板弱轴节点试件的耗能能力有所降低；加强梁柱交界面处的连接可减缓刚度退化速度、显著提高节点的承载能力和耗能能力。

Abstract

To study the seismic behavior of concrete-filled square steel tubular column to U-shaped steel-concrete composite beam joints with separated internal diaphragm

four joint specimens were tested under cyclic loading. The test parameters are the diaphragm type and the connection forms at the beam-column interface. The hysteric behavior

ductility

energy dissipation and deformation were analyzed and suggestions the designing the reinforced plate were provided. Test results indicate that the beam bending failure occurred in all specimens

and the hysteric curves show an inverted S-shape

with an obvious pinch effect. The displacement ductility coefficient ratio is between 2.3-3.1

the elastic limit of inter-story drift rotation is between 1/68-1/53

the elastic-plastic limit of inter-story drift rotation is between 1/28-1/19

and the equivalent viscous damping coefficient is between 0.12-0.16

indicating that the specimens show good deformation and energy dissipation capacities. Changing the type of diaphragm has little effect on the load-carrying capacity of the specimen

but compared with the traditional internal diaphragm joints

the energy dissipation capacity of the weak axial internal diaphragm joints is decreased. Strengthening the beam-column connection can alleviate the stiffness degradation and effectively improve the bearing capacity and energy dissipation capacity of the joints.
