摘要：
Due to the excellent capacities on crack-width controlling and deformation, the high strength steel wire mesh reinforced engineering cementitious composites (HSSWM-ECC) have been used as an ideal material in structure strengthening engineering. However, limited literatures are available on the interfacial bond-slip model and the interfacial load carrying capacity between HSSWM-ECC and concrete. In this study, the modified hinged beam tests were carried out on nine groups of typical specimens to investigate the bonding performance at interface between HSSWM-ECC and concrete. A bond-slip model for the interface was proposed to predict the bond-slip performance between HSSWM-ECC and concrete, which was well agreed with the experimental result. Moreover, the micro-segment analysis method was developed considering the stress transfer at interface, accurately describing the mechanical characteristic of the interface. Finally, the analytical models for estimating the effective anchorage length and the interfacial load carrying capacity of the interface were established.
