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

Figure 24

Dynamic stress-plastic strain relationship of the steel at the locations of the plastic hinges. (a) Simply supported W150 × 24 with bending about the major x-x axis. (b) Propped cantilever W150 × 24 with bending about the major x-x axis. (c) Propped cantilever W150 × 24 with bending about the minor y-y axis. (d) Simply supported W200 × 71 with bending about the minor y-y axis.
