RCC structures subjected to spatial blast loading

The principle of building design is to achieve the assigned objectives under the prescribed demand. Cases of large-scale damages to structures due to unpredictable, higher levels loading, arising out of environmental loading; blast loading is one of them. The purpose of this research is to calculate blast parameters by analytical approach and obtain the pressure variation on different faces of building using IS:4991-1968. Three explosion weights (100 kg , 500 kg & 1000 kg) are exploded in three different standoff distances (15m , 30m & 45m) & at 0m , 6m & 12m vertical in air. Blast parameters & pressure variation on different faces of building are calculated for different explosive weights & respective distances. In the last step analysis of building is made through software analysis.
