单面叠合剪力墙金属连接件拉拔性能试验研究

Experimental Study on Pull-Out Performance of Metal Connectors of Single-Sided Superimposed Shear Wall

文中设计了单面叠合剪力墙的钢筋连接件和不锈钢连接件,对不同端部构造形式的连接件进行单侧轴向拉拔试验。对其抗拔承载力、承载力-滑移曲线等进行分析,结果表明,破坏模式以混凝土锥形体被拔出为主,金属连接件的抗拔承载力均在16.92 kN以上。对金属连接件的抗拔承载力进行了计算,对比得出抗拔承载力试验值为计算值的0.92~3.17倍。

In this paper,the steel bar connectors and stainless steel connectors of single-sided superimposed shear wall are designed,and the single-sided axial pull-out test is carried out on the connectors with different end anchoring structures.The pull-bearing capacity and loaddisplacement curve are analyzed.The results show that the failure mode of the specimens is mainly the extraction failure of the concrete cone.The pull-bearing capacity of the metal connector is above 16.92 kN.The pull-out bearing capacity of the metal connector was calculated by formula.The results show that he test value of the pull-out bearing capacity was within the range of 0.92~3.17 times the calculated value.
