NUMERICAL SIMULATION OF BOND-SLIP MODELS BETWEEN FRP AND MASONRY IN PULL TESTS
The retrofitting of masonry structures with near-surface mounted (NSM) FRP plates and externally bonded (EB) FRP plates has proven to be an innovative and cost effective strengthening technique. The behaviour of such FRP-strengthened masonry structures is often controlled by the behaviour of the interface between the FRP and masonry, which is commonly studied using a pulltest. In this paper, several masonry prisms in pull tests are simulated numerically using a distinct modelling approach in which bricks and mortar are simulated individually while the bond-slip behaviour at the FRP-to-masonry interface in pull tests is simulated by either solid continuum elements where detailed information of the interface can be modelled directly, or by contact relation models where the FRP-to-masonry interface is described as a type of contact surface. Comparisons between the various predictions and test results from experimental pull tests of NSM and EB FRP plates in masonry prisms are presented to demonstrate the efficiency and accuracy of the interface model and contact model.
