摘要

对混凝土预制结构中用于连接钢筋的灌浆套筒搭接接头的性能进行了研究。共测试了63个试件，不同的杆径和搭接长度，在拉伸荷载下进行了试验。讨论了试件的破坏模式、极限抗拉强度值和荷载-位移曲线。提出了计算平均搭接粘结应力和临界搭接长度的两个方程。

Experimental study of grouted sleeve lapping connector under tensile load

The performance of the grouted sleeve lapping connector that is used to connect reinforcement bars in a precast concrete structure is studied. A total of 63 specimens, varying in bar diameter and lap length, were tested under tensile load. The failure modes, ultimate tensile strength values and load-displacement curves of the specimens are discussed in the study. Two equations are proposed for calculating the average lapping bond stress and critical lap length.
