Abstract

The detonation of an explosive charge extremely near or above the ground could be devastating causing deformation to the structural frame of the building, cracking of walls, exploding huge areas of windows and shattering all kinds of life saving systems. Depending upon the type and size of explosive used, the possible structural collapse happens when the blast waves produced during explosion, impacting the structure over time. This paper presents to study the characteristics of blast waves and understanding the relationships between various parameters considered in blast loading such as incident overpressure, reflected overpressure, phase duration and scaled distance. Analysis and quantification of uncertainties of the TNT equivalency of different explosives with respect to pressure and impulse observed. Focus was given to formulate an empirical equation from the extracted experimental data considering the influential parameters affecting the blast resistant design that governs the modeling of blast loads. This equation could help in predicting the safe distances beyond which the blasting of different types of explosives would cause minimum impact on the structure. Thus for designing a structure to be resisting blast weight, the foremost important task is to have a realistic overview about the prediction of pressures impacting on a structure and this paper gives essential outline of the detonating effects due to various types of explosives on structures.
