Abstract

Contact blast is being considered comparatively easier to dismantle slabs. Fanatics and radicalized elements also use contact blast devices to create panic in society. It is obvious that the anti-blast resistance of the slab would depend upon its materials, geometry, and boundary conditions. In addition to cracking, typically, the slabs under contact blast suffer from local damage in the form of concrete crater, scabbing, perforation and rupture of the reinforcement (r/f). Anti-explosion response of reinforced concrete (RC) slabs supported on two opposite edges and all four edges has been extensively investigated through experimental and computational studies. This information is readily available in the literature. However, there is a lack of research on the anti-contact-explosion response of slabs supported on three edges. In order to accomplish this goal, a computational analysis is carried out utilizing the Abaqus software. The study extends with a validated model of a square slab by supporting it on three edges or all four edges and is subjected to a concentric contact explosion. The process of explosion is described by taking into account the specific structure of the software. The results suggest that the boundary conditions (BCs) of the slab play a crucial role in determining the damage pattern and its extent when exposed to a contact explosion.
