Abstract

This paper presents an experimental investigation conducted on masonry walls subjected to an out of- plane loading or normal pressure. This study has multiple objectives. It allows, first to quantify the bearing capacity in the case of uniform pressure in quasi-static loading case, and thus to highlight the associated modes of rupture, and secondly to estimate the improvements in terms of global behaviour when the structure is reinforced by Carbon Fiber Reinforced Polymer (CFRP) layers. A gain higher than 140% is observed for the bearing capacity. Finally, numerical simulation with the discrete element method is conducted and compared to the experiments. Good agreement between the numerical and the experimental results is obtained.
