Abstract
In the current scenario of insecurity from different sources, the role of the compound wall is more important than ever. In addition to stability, the strength of such walls from the explosion point of view is of considerable interest to the engineers. In this paper, the finite element simulations of 6000 mm × 2500 mm × 350 mm (length × height × thickness) free-standing compound unreinforced brick masonry wall subjected to experimental blast peak overpressures available in the open literature are performed. A high-fidelity FEM-based software package ABAQUS/CAE has been called for and a continuum/macro-modeling technique is adopted to optimize the computational time. Damage is simulated considering the available concrete-damaged plasticity (CDP) model for the non-linear response of the walls. Dynamic responses including maximum displacement, damage dissipation energy, and crack/damage patterns have been evaluated for the scaled distances of 2.28 and 1.81 m/kg1/3. The height of the burst is 1250 mm from the ground. With the objective to improve the blast performance of the wall, a 230 mm thick reinforced concrete (RC) wall with a 70 mm wide cavity is considered in the study. To dissipate the explosion energy, bricks on edge, and sand are also taken as softcore materials in the cavity of the wall. The cavity is interrupted by the cross RC elements at an interval of 1.10 m. Analyses results have been discussed and a novel design of the blast-resistant free-standing wall is recommended.
