Analysis of Blast Load on Structure using SAP2000

Abstract

A bomb blast inside or quickly close-by a structure can cause disastrous harm on the structure's outside and interior auxiliary casings, falling of dividers, smothering of extensive fields of windows, and closing down of basic life-wellbeing frameworks. Death toll and wounds to inhabitants can result from numerous causes, including direct impact impacts, auxiliary breakdown, flotsam and jetsam effect, flame, and smoke. The circuitous impacts can consolidate to repress or counteract auspicious departure, along these lines adding to extra setbacks. Furthermore, significant disasters coming about because of gas-substance blasts result in extensive powerful loads, more noteworthy than the first plan loads, of numerous structures. Because of the risk from such extraordinary stacking conditions, endeavors have been made amid the previous three decades to create strategies for basic examination and configuration to oppose impact loads. Studies were directed on the conduct of basic cement exposed to impact loads. These examinations step by step upgraded the comprehension of the job that auxiliary subtleties play in influencing the conduct. The steel structure and concrete structure subjected to blast loads was examined and then the results were compared. The software SAP 2000 was used to model the structures with different boundary conditions. For the load calculation, Kinney Graham approach was used to determine peak reflected pressure. Further, with time, pressure was applied and time history response was obtained for steel structure and concrete structure.
