Study the impact of blast load on G+7 multistoried RCC structure with varied distances

Abstract

Nowadays, due to increased terrorist activity throughout the world, Blasts have been taking place irrespective of the location. In order to withstand such blasts, the structure should be designed such a way that the detailing and grade of concrete should be improvised. This current study includes the behaviour of G+7 multi storied structure subjected to 100 kg TNT explosion which is assumed to be taken place at 10 m, 20 m, 30 m and 40 m away from the structure. As per IS 4991:1968, Blast Pressures are calculated manually and executed in STAAD Pro tool. The results of Blast loads on structure is compared in its static condition and redesigned the structure to sustain the Blast loads.
