In this paper, guidelines such as UFC-3-340-02 have been developed to design structures against explosive loads. In UFC regulations, a number of simplistic assumptions are considered in order to calculate the explosive loading pattern of building constructions. If one of these assumptions is violated, an explosive loading pattern of building materials should be obtained using laboratory and numerical methods. The change in the corners of the building (non-impermeable corners of the building cone) violates one of the assumptions of the UFC Code. In this study, we simulate explosive phenomena in the AUTODYN hydro codeto calculate the explosive loading pattern of the side faces of the building. The effect of four variables including the left and right coronal angles from the front, the forward aspect ratio and the explosive space distance from the building on the side facesimpact explosion pattern using 25 Taguchi methods suggested. As a result of this study, the opening of the cornea from the front directly affects the maximum and impulse pressure on lateral faces and the speed of the wave transition.
