Summary

The goal of this study is to focus on the analysis of blast wave damage to structures when blast wave is consequence of explosive charge detonation. The objective is to propose useful tools to predict charges on structure. All experiences are realized in laboratory. The experimental investigation consists in simulating a detonation of a stoechiometric propane-oxygen mixture at ground level or at higher altitude.

The study is going to give us experimental data on blast wave effect on a structure. For that, two types of structures frequently found on industrial site are going to be used: a parallelepipedic structure and a cylindrical structure, both with known dimensions.

Finally, the important point of the problem is to determine an energetic equivalence between TNT and gas used in the experiments, in order to model TNT explosions at full scale by gazeous explosions at reduced scale.
