Abstract:
In order to investigate the bonding and anchoring performance of high-strength stainless steel wire mesh in engineered cementitious composites (ECC), three parameters of transverse steel strand spacing, relative anchorage length and steel strand diameter were considered, and a total of 51 specimens in 17 groups were designed and carried out by the uniaxial pull-out test. The results show that the setting of transverse steel strand has obvious ductile failure characteristics. The transverse steel strand spacing has little effect on the bond strength, but the length of ductile strengthening section (ductility) increases with the decreasing of transverse steel strand spacing. The peak average bonding stress between the steel wire mesh and ECC is negatively correlated with the anchorage length and the steel strand diameter. The ductility increases with the increasing of the steel strand diameter, but decreases with the increasing of the anchorage length. The test results and analysis verify that the critical anchorage length calculation of the steel wire mesh in ECC can be calculated by using the critical anchorage length formula of a single steel strand.
