Abstract: Blast loads caused by explosives are unexpected loads. These loads cause huge damage to the structure and decrease the strength and durability of structure, especially for elevated buildings. Therefore study of such loads is of major importance. In the present study, G+10 floors with second, third and end bays is modelled using ETABS and sudden impact dynamic load analysis is carried out. The analysis is carried out on the face directly exposed to the blast load for 7 building models. The blast loads are obtained with the help of TM5-1300 manual as well as ATBLAST software and Structure is designed in ETABS software by non-linear time history analysis. The results of this study help in understanding the behaviour of tall structures in terms of drift, displacement, joint acceleration and shear. Observations show that Model 7 is found to have extreme shear, storey displacement and inter-story drift. The research on examination of tall structures subjected to explosion is helpful in coming up with a better, cost-effective design for blast resistant structures.
Keywords: Explosives, ETABS drift, displacement.
