Abstract

This manuscript presents a discrete crack approach enabling simulation of the progressive process of crack localisation and propagation, as well as its interaction with debonding of fibre-reinforced polymer (FRP) composites from concrete substrates. The numerical approach has been implemented with a non-iterative algorithm to efficiently overcome convergence difficulties produced by different sources of material non-linearity, such as concrete crushing and cracking, yielding of steel reinforcement and debonding of the FRP. The accuracy of the model has been validated against experimental results carried out on one-way simply-supported FRP-strengthened RC slabs, thus highlighting the ability of the proposed model to adequately capture the behaviour of the strengthened slab system.
