- Over the last few years, a huge amount of effort has been spent on developing numerical models to improve knowledge of methods to strengthen concrete and brick structures under various conditions. This paper evaluated the ability of the Discrete Element Method (DEM) to accurately predict the mechanical behavior of brick masonry. Two different specimens were tested for compression and direct shear, with and without polyurea reinforcement of the brick masonry. Detailed numerical models of the brick masonry were generated using the commercial software Three-Dimensional Distinct Element Code (3DEC) to compare the laboratory test results against simulation for both cases. The numerical and experimental results were found to be in good agreement, which demonstrates the efficiency and stability of the DEM for simulating brick masonry behavior. Another purpose of this research was to evaluated the effect of parameters on the numerical model, including mesh size, material cohesion, friction, and dilation. These important findings can be used to calibrate material model parameters for strengthening brick masonry in the future. ? 2022 Elsevier Ltd
