Analysis of the in-plane shear behaviour of FRP reinforced hollow brick masonry walls

This is the authors' abstract. We don't add key points for this paper.

This paper presents an experimental as well as a numerical analysis of the in-plane shear behaviour of hollow, 870×840×100mm masonry walls, externally strengthened with FRP composites. The experimental approach is devoted to the evaluation of the effectiveness of different composite strengthening configurations and the methodology consists in the diagonal compression of masonry walls. The numerical study assesses the stress and strain state distribution in the unreinforced and strengthened panels using a commercial finite element code. The effect of FRP reinforcement on the masonry behaviour and the capability of modelling to forecast a representative failure mode of the unreinforced and reinforced masonry walls is investigated.
