In this study, we have created a microscopic model of an unreinforced clay brick masonry wall, 5 m × 2.80 m × 0.23 m. The wall is braced with two RCC columns having nominal reinforcement. The main focus is to examine the behavior of the wall when imperilled to near-field blast, while varying the axial compression. Three walls have been simulated using the same brick units but with varying strengths of joint-mortar. These strengths are 2.50, 5, and 7.50 MPa. Each wall model is exposed to different levels of axial compression, specifically 9, 30 and 51 kN/m. These axial compressions correspond to the 3rd storey, 2nd storey, and 1st storey wall of a 3-storey masonry structure, respectively. Simulations are conducted utilizing a precise software application called Abaqus, hiring Concrete-Damage-Plasticity (CDP) model to analyze the effects of a 10 kg-TNT explosion at a proximity factor of 0.464 m/kg1/3. Based on the research findings, it is suggested that when subjected to explosion load, the wall exhibits a minimal displacement response when reinforced with joint-mortar of strength 5 MPa for moderate axial compression, and strength 7.50 MPa for higher axial compression.
