Behaviour of deformable blast walls for protective structural design

The response of deformable reinforced concrete blast walls is investigated using the commercial finite element code LS-Dyna. The design of the wall is based on 20 kg of TNT-equivalent mass of explosive material. The amount of explosive material is further increased and the damage pattern of the wall is demonstrated in the finite element analysis results. Significant wall failure occurs when the amount of explosive material is increased well beyond the 20 kg design level.
