Response of Reinforced Concrete Structural Com-ponents Subjected to the Blast Loading

Abstract

A explosion within or nearby a structure causes disastrous damage to internal and external structural system. These explosions cause masonry walls to collapse, blowing out large stretches of windows and closing all critical life-safety systems. Casualty occur due to direct contact with blast, structure failure, buried under debris, fire or smoke. Major catastrophes from gas-chemical explosions are cause for rise in large dynamic loads greater than the actual design loads. Efforts have been made to develop design and analysis methods to reduce the threats from extreme loading conditions. Study carried out on response of concrete under impact loads, enhance the understanding the role of structural design play in affecting the behaviour. Analysis and design of buildings under blast loads requires detailed study of dynamic response of structure. In this paper, the response of RC frame subjected to internal blast loads is studied. The RC frame was modelled in a finite element software (Abaqus). For the response evaluation, an internal explosion was first created inside a room and the equilibrium state was determined.
