Behaviour and Failure of Steel Columns Subjected to Blast Loads: Numerical Study and Analytical Approach

Figure 26

Comparison between analytical method and ABAQUS predictions of critical impulse-axial force curve for steel column section W150 × 24 with simply supported (S.S.) and propped cantilever (Prop.) boundary conditions and with blast pressure to cause bending about major and minor axes of the column.
