Abstract: This paper presents the findings from a programme of research, which explores the opportunities offered by an effective of aluminum foam panels as s sacrificial cladding design for the curved elevation technique of the strategic installations to alleviate the blast waves. Infinite element simulations have been carried out in order to investigate the behaviour of aluminum foam panels subjected to blast loading. Each simulation was used to calculate the pressure and impulse transfer from the blast loading, as assessed using the AUTODYN software in 2D & 3D V3.1.17. The main contribution achieved in this paper declared in the results of the simulations. The analysis of the simulation output reveals that the aluminum foam panels technique offer a significant reduction for impulse and pressure values in the effects of the blast waves on the structure. This technique can be used without affecting the functionality of the structure or the street. Also offers benefits of shielding and robustness whilst having good aesthetic appeal and other architectural advantages.
