Abstract: The swift in population development and urbanization have made a huge interest in the safe house and development of new materials. Masonry walls are the real segment in the housing sector and it has fragile attributes and shows poor performance against the uncertain loads. The 3-D sandwich walls are such system, which is more suitable for ease and speedy wall construction. The idea of a sandwich 3-D wall is to combine thin and durable facings with a light-weight core material, i.e. EPS (expanded polystyrene) which is suitable for sound and heat Insulation. Shear connectors are introduced to provide integrity and to transfer the loads. This paper reports the numerical evaluation concerning the effects such as energy absorption of core material, transfer of shock wave and the displacement of adaptable sandwich walls subjected to blast loading. The numerical model is generated using ABAQUS software to determine the dynamic response of sandwich 3-D walls under the blast loading and is compared with the response of masonry wall.
