Blast Resistant Analysis and its Impact on Buildings using ETABS

Abstract

Day to day advancement in technology gave scope to build high rise structures which dragcentre of attention from all other normal structures. This indistinctly emphasis terrorist to focus on giant structures, like that happened with the Taj palace hotel, India and twin towers, America. Even though it is not a realistic or cost-effective choice to build the structure to be completely blast resistant. Improvements can make to both new and existing structures to lessen the impact of a bomb. The goal of this research is to shed light on blast-resistant building design theories, as well as the enhancement of building security against the impacts of explosives in both the architectural and structural design processes. And also the design methodologies that should be used.  Having a better grasp of explosives and explosion properties can help to develop more efficient blast-resistant structures.  Therefore the consequences of blast loads on structures are an unsmiling matter that should be taken into consideration in design.This paper presents architectural planning, blast load analysis of multi storey RCC building in Zone II, Zone III, Zone IV, Zone V using ETABS software as per IS 4991-1968 guidelines. The force at different parts of the building from the point of impact is calculated. The change in storey shear, displacement and storey drift are calculated and compared in between Zone II, III, IVand V.The analysis of the structure is carried out using two loading combinations separately asDead Load, Live Load, Earthquake Load, Wind Load andBlast Load.
