ANALYSIS OF TNT INDUCED SURFACE BLAST LOADING ON REGULAR G+4 RCC FRAMED BUILDING

Abstract

Since past few decades there had been an increased emphasis on designing a structure for blast loading. This is due to increased terrorist activities throughout the world. While the standard structures in most of the countries are designed for the seismic loading, so as to mitigate to a certain extent the catastrophic damage caused by nature, anthropogenic blast loading is proving to be far more catastrophic due to lack of proper techniques and measures to counter its ill- effects. However there had been continuous efforts by the researchers to predict, analyze and mitigate blast loading and its effects.As a result the building codes of various countries have included provisions for the design and construction of blast resistant buildings. Also the works of various researchers claim that by default, the structures designed to resist the seismic loads perform better in resisting blast loading as well. In this study an attempt has been made to analyze blast loading on a regular RCC framed structure already designed for the seismic loading (in accordance with the relevant Indian codes), and to study the difference in various building parameters related to response of building.
