| Abstract |
Interest in the behavior and resistance of structures for blast mitigation of high explosive charges is growing more and more. In this paper, the residual axial resistance of steel compressive members damaged by blast loading was precisely evaluated using the explicit-to-implicit finite element analysis method. The empirical blast loading, the blast-induced damage in terms of structural deformation, and the members' strength against axial loading were simulated. The effects of the structural shapes and the scaled distance from explosive charge to structure on the blast response and residual capacity of the compressive members were estimated using parametric studies. The linear relationship between blast-induced horizontal deformation and residual axial strength of blast-damaged steel compressive members carrying the same plastic moment capacity was observed based on the analysis results. |
