ABSTRACT
For the analysis presented here, threat parameters were determined using the recommendations provided by Conrath et al. (1995). The aggressor tactics was assumed to be a stationary vehicle bombwith an equivalent TNT value of 90.7 kg at 3.96 m from the face of the column. The threat parameter satisfies the criterion of a medium design basis threat severity level. The corresponding blast pressure-time histories were determined by FEFLO, a general purpose computational fluid dynamics programdevelopedby theCenter for Computational Fluid Dynamics at George Mason University. FEFLO is based on adaptive unstructured grid methodology and is capable of producing timeaccurate solutions for non-linear geometries and wide range of flow regimes (Löhner et al. 2001). Pressuretime histories were calculated for 606 target points throughout the height of the column. Figure 2 shows the plot of the maximum (peak) pressure-time history observed at the column next to the charge.
