Assessment of non linear bond laws for NSM systems in concrete elements
Ceroni, Francesca; Barros, Joaquim A. O.; Pecce, Marisa; Ianniciello, MarcoIn this paper the numerical FEM model developed to simulate the behaviour of the NSM strengthening system for concrete elements is presented. The plane model introduces the non linear bond law of the system by an interface element between the composite reinforcement and the concrete considered linear. The results of two experimental programs are analysed and used to calibrate the parameters of the bond shea...
Assessment of nonlinear bond laws for near-surface-mounted systems in concrete ...
Ceroni, Francesca; Barros, Joaquim A. O.; Pecce, Marisa; Ianniciello, MarcoThis paper presents a numerical plane Finite Element (FE) Model for use in simulating the behaviour of different types of Near Surface Mounted (NSM) Fibre Reinforced Plastic (FRP) strengthening systems for concrete elements. Based on a nonlinear bond law for simulating the behaviour of the FRP reinforcement-adhesive-concrete interface, the model employs an interface element between the NSM FRP reinforcement and...
