This paper details the development of an engineering assessment procedure for reinforced concrete (RC) column failure when subjected to time-variant coupled axial and lateral loads due to internal building detonations. This is based on a comprehensive parametric study conducted using an advanced uncoupled Euler–Lagrange numerical modeling; splitting the structural and flow solvers for maximum integrity and accuracy. The column assessment charts discussed in this paper provide threshold combinations of TNT equivalence and stand-off distance for a range of column residual axial capacity levels corresponding to two key internal blast environments: Vented and contained. This will be of direct relevance to both practitioners and researchers involved with protective design of civilian and military buildings.
