Abstract: Three-dimensional (3D) numerical modelling of blast subjected to reinforced concrete wall is studied in this paper. The Arbitrary Lagrange Euler (ALE) solvers approach is employed for the interface analysis between air and structure in AUTODYN commercial software. The previous published empirical and semi empirical methods are compared on the blast pressure profile impacted on the wall surface. Besides, the effects of air volume size, the effects of air grid mesh refinement also assessed. Initially, the 3D numerical blast pressure is validated with the blast pressure test conducted at Fort Leonard Wood Army Base for further blast pressure investigation. From series of simulation conducted, the blast pressure at the bottom part on the wall surface experienced the highest pressure. Contrary on the empirical and semi empirical, the blast pressure distribution is identical either at the top or bottom surface of the wall.
