摘要：
Twenty-seven standard push-out specimens which were designed based on orthogonal design method to study bond-slip behavior between section and RAC (Recycled Aggregate Concrete) in SRRC (Steel Reinforced Recycled Concrete). Test results showed: In terms of failure mechanism and failure pattern, SRRC was similar to SRC, experiencing no-slipping, slipping, destroying, decline and residual stage. Average bond strength of SRRC was influenced by RCA, RAC strength, embedment length as well as thickness of concrete cover of SRC in some degree. Based on test data, the calculation formula of bond strength was established by statistical fitting. Compared with the test results, the calculation results could satisfy computational accuracy.
