摘　　要：基于夹芯保温叠合剪力墙钢筋连接件的力学性能,设计了5种类型的钢筋连接件,并进行抗拔试验,研究了钢筋连接件的破坏形态、抗拔承载力、荷载-位移关系等。基于试验现象和数据,给出了钢筋连接件的抗拔承载力计算公式。结果表明:试件的受拉破坏形态多为混凝土锥形体拔出破坏;抗拔承载力计算公式在一定程度上反映了其实际承载力,用该方法计算的抗拔承载力用于实际工程中较为安全。Five types of reinforcement connectors were designed based on the mechanical properties of sandwich insulation laminated shear wall reinforcement connectors,and the tensile test was carried out to study the failure form,pull-out bearing capacity,load-displacement relationship of reinforcement connectors.Based on the test phenomena and data,the calculation formula of the pull-out bearing capacity of reinforcement connectors was given.The results show that the tensile failure mode of the specimens is mostly the pulling out failure of concrete conical body.The calculation formula of pull-out bearing capacity reflects the actual bearing capacity to a certain extent.It is safe to use this method to calculate pull-out bearing capacity in practical engineering.
