Behaviors of a Blast Wall According to the Angle of Vee Stiffener

This study has been carried out to investigate the influence of inclined angle of vee stiffener used on blast wall structure. In order to prevent the structural buckling, the vee stiffeners is employed and placed on the compressive region. A higher peak pressure was applied in order to investigate the buckling phenomena on the corrugated panel with vee stiffener. The inclined angle of vee stiffener was varied from 15° to 90°. The results show that an alteration of inclined angle has a considerable effect on the dynamic response of the blast wall structure, the deformed shape and the effectiveness of the stiffener due to the absorbed plastic strain energy. The best inclined angle of the vee stiffener is also determined.
