Abstract
In this paper, the blast resisting performance of partially reinforced CFT columns was compared with the normal CFT columns to evaluate the effect of reinforcing with steel plates. Autodyn which is a specialized hydro-code for analysis of explosion and impact was used to simulate the structural behavior of the CFT columns under the blast loadings. The interaction between concrete and surrounding steel plates was modeled with friction and join option to represent the realistic damage of columns. According to the analysis, the partially reinforced CFT column showed enhanced blast resisting performance than the normal CFT columns. Also the improvement of blast resisting performance was depended on the height of reinforcing steel plates.
