Calculation and analysis of interfacial peeling capacity between steel wire mesh reinforced ECC and concrete

Abstract

Abstract: In order to explore the interface bonding performance of steel wire mesh reinforced ECC and concrete, the interfacial bonding performance of a total of 21 beam specimens designed and manufactured by 7 groups were tested with concrete strength, interface bonding length and bond width as test parameters. The results show that there are two failure modes: interface stripping and strand rupture. The interface peeling capacity increases with the increase of concrete strength. In the range of effective bonding length, the interface stripping capacity increases with the increase of bonding length, but has no obvious effect on the interface bonding strength. The bonding width of the interface has no significant effect on the tensile strength of the interface, but the bonding strength decreases. Based on the statistical analysis of effective bonding length test, the prediction model of the interface stripping capacity between steel wire mesh reinforced ECC and concrete was established, and the verification analysis showed that the prediction formula had good applicability.
