Abstract

Recently, explosions, collisions, and fires have occurred frequently around the world due to terror attacks, and impact accidents. Particularly, since the 9.11 terror attack, public anxiety heightened due to lack of safety in our society. The incidents can be viewed as examples of possible extreme loading scenarios that can occur in structures and infrastructures. Among all of structures and infrastructures, prestressed concrete containment vessels (PCCVs) are the most vulnerable structures from terrors and accidents. Therefore, in this study, finite element software LS-DYNA and MIDAS FEA, are used to evaluate of PCCVs applied with blast induced fire loading resistance. Since the blast test on a full-scale PCCV is not realistically possible, it is necessary to develop a precise simulation tool to accurately evaluate the damage level of a full-scale PCCV. This study aims to improve the accuracy of the simulation tool by calibrating numerical software using experimental test data. Then, the parametric study is conducted according to the explosive charge weight, standoff distance, and concrete compressive strength of a PCCV using calibrated blast and fire simulation tools. Based on the study results, the level of damage assessment to PCCVs applied with blast-fire loading can be precisely evaluated.
