Experimental study of grouted sleeve lapping connector under tensile load

Qiong Yu, Zhiyuan Xu

Abstract

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.

Keywords
precast concrete structure, sleeve confinement, bond-slip, lap length
