Masonry composed of clay bricks and mortar is widely used as a construction material for both structural and non-structural walls. However, due to their weight and low blast capacity, unreinforced brick masonry walls can present a significant hazard to building occupants when subjected to accidental or deliberate blast loads. There are considerable uncertainties associated with the material strength, structural response, threat scenarios as well as expected damage. In this paper, Monte-Carlo simulation and probabilistic methods are used as the computational tool that incorporates uncertainties associated with blast loads and material properties for various potential threat scenarios. A plastic damage model has been used for brick and mortar and the numerical model was validated by a comparison with field test data. The structural reliability analysis calculated: (i) variability of structural response and (ii) damage risks for brick masonry walls subject to various explosive threat scenarios.
