摘要：Traditional design research typically focuses on the design and construction of new structures, buildings and structures. A large proportion of existing concrete structures have wear problems. The longitudinal shear stress created by a load in reinforced concrete at the boundaries of concrete and reinforcement is considered. The parameters of numerous variables affecting this relationship are given, including the strength and cover of concrete, the type of reinforcement, the use of transverse reinforcement, the state of the reinforcement surface, the length of the anchorage, the stress state in the reinforcement, loading, and environmental influences. An empirical model obtained by the best comparison with test results is presented. The results of the mutual influence between loading and corrosion of reinforcing steel are presented. Research results show that loss of bond caused by structural failure becomes more critical compared to other types of failure as the life of the structure increases.
