The terrorist attack on buildings or in its surrounding has increased steadily in recent years. Usually, the blast might occur in the ground level thus columns in ground-level undergo impact loading. Since steel and composite type of columns are used nowadays, the nonlinear dynamic analysis of blast loading in such columns has become highly important. This helps to understand the impact of explosions on columns. In this study, RC column, steel and composite column with equal height are designed for the same load-carrying capacity and Finite Element Modeling using ABAQUS. Time History Method is used to analyze the columns. This study aims to simulate and compare the non-linear dynamic analysis of blast loaded concrete and steel structures. The examination of the result exposes the vulnerability in the steel column and the effectiveness of the composite column. RDX of charge weight 100 kg and standoff distance of 1 meter is considered for analysis. © 2021 Institute of Physics Publishing. All rights reserved.
