material is 400 MPa. Assuming rigid-plastic response and
all deformation concentrated at the mid-span plastic hinge
find the maximum displacement Wmax using equivalent
SDOF system. Find also the maximum dynamic reaction
force at the support. Assume the blast load to be
impulsive, and the density of steel is 7800 kg/m³.
