Abstract
Now in the recent time of terrorism, structural engineers require new consideration of terrorist attack in the design standards. Modern day structures pose a unique challenge to designers due to increased terrorist activities. Bomb blasts, vehicular attacks, Arson, Armed based attack all may result into a partial or total collapse of buildings. The work undertaken is an attempt to recognize the behaviour of RC structure under series blast loading. A model of G+4 RC structures has been considered as a progressive collapse analysis. The RC building with effect of series blast loading is analysed by using linear static and dynamic analysis. The present study work will carry out the effective study of different parameters like; different types of explosive charges (5T-5T, 7.5T-7.5T, 10T-10T TNT) at 10 mt. stand-off distance, failure of structure element at storey level and the structure is checked for progressive collapse by using commonly available, widely used software SAP 2000 will utilize for analysis.
