摘要/Abstract

摘要： 模拟钢管混凝土柱节点区钢管壁－梁端混凝土剪力传递的界面进行了13个含抗剪阻力件的试件的抗剪试验试验参数为混凝土强度、剪跨比、阻力件的位置、排数和排距试验还考虑了纵筋销栓作用．试验结果表明在侧限条件下界面传递剪力能力大为提高．本试验为新型钢管混凝土柱节点的抗剪能力提供了可靠的试验依据可供节点设计时参考．

关键词: 钢管混凝土柱节点, 侧向约束, 抗剪阻力件, 局部承压强度, 双拱结构

Abstract: The results of a shear resistant test of13specimens are presented in this paper．The specimens were designed to simulate the stee-l concrete shear transfer interface of the concrete filled steel tubular（CFST） column-RC beam joint on which some shear bars were stuck to improve the shear resistant capacity．The parameters of concrete strength shear span ratio bar position dowel action etc．were taken into account in the research．The test results show that the shear bar may serve as an effective means for shear transfer．The experimental research also serves as a good reference to the design of the CFST column-RC beam joint．

Key words: concrete filled steel tubular column joint, lateral restraint, shear bar, local bearing strength, b-i arch action
