Abstract Engineering structures face the potential of encountering repetitive or multiple blast loads stemming from accidental explosions and terrorist attacks. However, current research in this field is still relatively limited, further investigation needed to understand damage mechanisms under explosions. Therefore, study explores resistance G‐HPC slabs reinforced with steel wire mesh (SWM) loads. The failure modes SWM‐reinforced slab were experimentally studied two consecutive (with explosive equivalents 1.6 3.2 kg, both at a standoff distance 0.4 m). results revealed that, after explosions, exhibited bulging minimal concrete spalling, showcasing overall integrity. Subsequently, numerical model was established, followed by comprehensive parameter analysis. analysis investigated effects SWM diameters grid size, arrangement SWM, sequence TNT on performance three findings that increasing diameter reducing size significantly enhanced Strategically arranging tensile zone reduced deflection. Furthermore, had notable impact energy absorption slab.
