COMPARITIVE ANALYSIS OF HIGH STRENGTH CONCRETE AND NORMAL STRENGTH CONCRETE COLUMN UNDER BLAST LOAD

Abstract

A bomb explosion nearby a structure can cause catastrophic damage on the structure's external and internal
structural frames, collapsing of walls, blowing out of large expanses of windows, and shutting down of critical life-safety
systems. Loss of life and injuries to occupants can result from many causes, including direct blast-effects, structural
collapse, debris impact, fire, and smoke. The indirect effects can combine to inhibit or prevent timely removal, thereby
contributing to additional fatalities. The analysis and design of structures subjected to blast loads require a detailed
understanding of blast phenomena and the dynamic response of various structural elements. This gives a complete
overview of the effects of blast on structures. The aim of this study is to prevent the collapse of the building Despite the
fact that, the magnitude of the explosion and the loads caused by it cannot be predicted perfectly, the most possible
scenarios will let to find the necessary engineering solutions for it. Present study includes the comparative study between
high strength concrete column and normal strength concrete column under blast load.
