|Title:||Modelling of the bond behaviour between FRP and Concrete under low slip rate||Authors:||Xu, Yuheng||Keywords:||DRNTU::Engineering::Civil engineering::Structures and design||Issue Date:||2017||Abstract:||The usage of externally bonded FRP system as a way to strengthened RC structures is increasingly popular in the past decade due to their high strength-to-weight ratio and chemical resistance. The failure at the bond interface of a FRP-strengthened RC structure can be modelled using a bond-slip model. Rather than doing the real experimental method of pull-out tests, a meso-scale finite element analysis was carried out to simulate the pull-out tests for a specimen subjected to low slip rate. The bond-slip model provides the peak bond stress and interfacial fracture energy which acts as the key indicators of the structural performance of an FRP-strengthened RC structure. After investigating the local response of the bond using its bond-slip behaviour, the global response such as the RC structure’s overall loading capacity could be included to give a more comprehensive assessment of the structure.||URI:||http://hdl.handle.net/10356/70944||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
