Moreover, residual strength capacity of the columns strengthened with steel channel is higher than the other models. The results showed that retrofitting significantly improves blast performance of the columns. The considered strengthening methods were different steel jacket configurations including steel angle, channel, and plate sections. Therefore, we can investigate the effectiveness of axial strengthening of column on its blast resistance capacity and residual axial strength. Strengthening configurations considered here were designed for enhancing axial capacity of RC columns. Accordingly, in this paper, the behavior of 6 different models of normal and strengthened RC columns under blast loading was evaluated using ABAQUS.

With respect to complexity, limitations, and high costs of experimental tests, analytical studies and software modeling can be good alternatives. Observed data of the members’ response under blast loading was used for validation of finite element modeling process using ABAQUS software. Four RC components, with identical geometry and material, with and without axial load were imposed to air blast. Therefore, an experimental explosion loading has been done on RC members by the authors. Hence, experimental tests could be the best method for evaluating structures under blast loading. Different factors can affect blast response of structural components.
