As social interest about unusual load like impact, blast etc is increasing, the analysis of structural behavior and assurance of safety under those unusual load are required. Becuase blast load is mostly estimated based on trinitrotoluene(TNT), the calculation of TNT equivalent mass of explosives is needed. Also, the blast load passes rapidly in a very short period of time and result in significant deformation of structures. So, it is difficult to analyze the behavior of structures using such a static analysis method. In this study, TNT equivalent mass of gas is calculated with reaction heat of gas, and behavior of structure is analyzed with explicit code. |
