Bond-Slip Performance between High-Strength Steel Wire Rope Meshes and Engineered Cementitious Composites
https://orcid.org/0000-0002-7951-8405
Engineered cementitious composites (ECC) are distinguished by ultrahigh ductility and multiple cracking. High-strength stainless steel wire rope (HSSSWR) meshes have been successfully applied to strengthening existing structures. Taking advantage of both ECC and HSSSWR meshes, HSSSWR mesh–reinforced ECC promises to be an innovative strengthening material for significantly improving overall performance of existing structures. In order to capture the bond performance between HSSSWR meshes and ECC, direct pull-out tests on HSSSWR meshes embedded in ECC were performed considering the effects of spacing of transverse wire ropes, bond length, and nominal diameter of HSSSWR. The influence laws of the considered factors on the bond behavior between HSSSWR meshes and ECC were investigated. The failure characteristics and bond-slip relationship between HSSSWR meshes and ECC were revealed through analyses of experimental results. A bond-slip model was proposed to predict the bond-slip behavior of HSSSWR meshes in ECC, which was verified to be acceptable by comparing it with test results.
