Experimental Study of Strain Clamps Crimped Under Unbalanced Condition

Abstract

In order to clarify the relationship between the efficacy loss of strain clamp joints and the crimping quality, three groups of clamp joints, crimped under unbalanced conditions at both ends, naming NY-240/40, NY-400/35 and NY-630/45 were selected and then subjected to tensile tests and X-ray inspection. After a detailed analysis of the experimental results, it can be seen that under the condition of unbalanced crimping quality, the efficacy loss all occurred on the side with better crimping quality, which provides an instructive reference for the crimping technique of strain clamps in actual project construction.
