ABSTRACT

There is a need to study and design blast resistance structures as the terrorist activities are increasing day by day for all important structures. In present day scenario, accidental or intentional blast may take place at any point of time. From the recent blast in India at Pulwama in 2019, Bogota city in Colombia 2019 and Mogadishu city in Somalia 2018, there was a huge loss for human life. Hence, it is vital to understand how structures behave when they experience blast loads. In this paper the effects and behavior of a G+5 symmetric Reinforced concrete building with surface blast for three different charge weights of 500, 1500 and 2500 kg TNT (Tri nitro toluene) assuming that the blast has occurred from a range of 10, 15 and 20 meters in lateral direction and analysis was done using SAP 2000 considering on the positive phase of the blast. Based on the results obtained from the study, response for variations in inter storey drift and energy absorbed by the considered structure is studied.
