This document summarizes a study that used finite element analysis to compare the lateral deflection of long and short side reinforced concrete columns subjected to blast loading. The analysis used ANSYS to model 8 columns with different transverse and longitudinal reinforcement. It found that the long side columns experienced significantly higher maximum lateral deformations than the short side columns. Ratios of short to long side column deformation ranged from 0.24 to 0.38 depending on the column. The study concluded that column length and orientation affects deformation under blast loading, with long side columns experiencing greater impacts.
