| Abstract | Failure modes of concrete structure due to blast load vary according to the point of detonation, stand-off distance and TNT charge weight. Especially columns are the key load bearing elements in concrete frame structures. They are typically weak not to long distance explosive loadings but to short distance loadings. In this study, the effect of blast loadings occurred within the short distance was analytically examined. Scaled distance which considers both stand-off distance and TNT charge weight and various arrangement of longitudinal reinforcements with the same sectional area were considered as variables in order to evaluate damage levels and define the relations among these variables with respect to residual strength of columns after blast. AUTODYN was used for the FE analysis. As results, denser arrangement of the longitudinal reinforcements using smaller diameter bars showed relatively better residual capacity. |
