| 摘 要： | 通过双面叠合剪力墙水平连接节点在循环剪切荷载作用下的试验,对界面连接钢筋的应变随剪切荷载的变化规律进行了分析。结果表明,双面叠合剪力墙水平连接节点界面连接钢筋的应变变化规律和现浇节点相同位置处的界面连接钢筋应变变化规律一致。根据剪切-摩擦理论对双面叠合剪力墙水平连接节点的抗剪机理进行分析,确定水平连接节点的抗剪承载力由界面混凝土黏结力、界面摩擦力和界面钢筋的销栓力组成,基于剪切-摩擦理论建立了双面叠合剪力墙水平连接节点的抗剪承载力计算公式。

The analysis of shear capacity on horizontal connections of the double-superimposed shear wall based on shear-friction theory |
| |
| Abstract: | The strain of connecting reinforcement versus shear load relationship was analyzed, based on an experimental study on double-superimposed shear wall horizontal connections subjected to reversed cyclic shear deformations combined with vertical loads. The results showed that the variation trends of connecting reinforcement strain in double-superimposed shear wall horizontal connections were identical with that in cast-in-place horizontal connections. The shear mechanism of double-superimposed shear wall horizontal connections was analyzed based on shear-friction theory, the ultimate shear capacity of the double-superimposed shear wall horizontal connections was determined by the bond force at the interface, the interface friction and dowel action of shear connecting reinforcement. The proposed calculation formula for shear bearing capacity of the double-superimposed shear wall horizontal connection was derived based on the shear-friction theory. |
