방폭 변전실에 대한 외부 폭발 시뮬레이션 및 안정성 평가 연구

Many structures in the world have experienced severe damage due to explosion in recent years. As this blast loading is impact load of short duration with high pressure, accuracy of analysis results about blast loading is significantly important. This study performs mechanical behavior of Prefabricated Packaged Local Electrical Room under blast loading using ABAQUS/Explicit as refer to blast loads calculation method of the literature. And shows adequacy of analysis technique through comparison and analysis using CONWEP of ABAQUS. It presents therefore the base about analysis of complex structure involving important system understanding accurately blast phenomenon.
