Blast Mitigation Effects on Facade System with Projections Utilizing Fluid-Structure-Fluid Interaction

Abstract

Abstract Various studies have been conducted on facade system exposed to blast loading have been explored in various studies. Studies conducted are limited to interaction between the fluid and solid domain neglecting the coupling effects of both domains. The impact upon interacting with a free standing will cause the structure to displace its position in the direction of the impact which will decrease the impact upon the structure. At the same time, the impact induced behind the structure will further reduce the effect of impact. This impact generated will marginally counteract the reduction of pressure on the structure. The displacement of the structure as well as shock-wave generated play a major role in reduction of impact on stationary structure. The effects of stress propagation within the structure have been ignored.
