The grouted sleeve splice is a competitive in the prefabricated structure that plays key role ensuring stability of whole structure. Despite large amounts experiments performed, its force mechanism has rarely been explored. In this study, novel method was developed to calculate constitutive model splice, and comprehensive understanding analyzed. Tensile tests 24 specimens were conducted explore...

Understanding the mechanism of progressive debonding bolts is great significance for underground safety. In this paper, both laboratory experiment and numerical simulation pull-out tests were performed. The experimental test specimens prepared using cement mortar material, a relationship between strength bolt uniaxial compressive (UCS) material specimen was established. locations crack develope...
