摘要

研究了12个注浆接头在拉伸载荷作用下的变形特性。测试变量包括拼接杆的直径和类型以及拼接套筒的尺寸。建立并验证了基于有限元方法的接头模型，并利用该模型研究了套管长度对注浆接头变形特性的影响。套筒长度对接头的破坏模式有显著影响，进而影响接头的变形特性。提出了一种建议，通过使用与杆断裂破坏模式相关的临界套筒长度来最大化特定接头的变形特性。

Effect of sleeve length on deformation properties of grouted splices

Tests on 12 grouted splices were performed to investigate their deformation properties under tensile loading. Test variables included diameter and type of spliced bars and the size of splicing sleeves. Finite element method based models of the splices were built, verified and used to investigate the effect of sleeve length on the deformation properties of the grouted splices. The sleeve length significantly affected the failure modes and further affected the splices’ deformation properties. A recommendation was proposed to maximize deformation properties of a specific splice by using a critical sleeve length associated with failure mode of bar fracture.
