A braced frame steel building is to be designed to resist blast
loads. The building is assumed to be at “medium” risk of a placed
bomb. Individual members in the building are to be analyzed as
separate one degree-of-freedom systems. Consider a W14x34 steel
column having a yield strength of 50 ksi. The building floors are
12 feet between story levels. The column is pinned at both ends.
The column supports exterior cladding; the bays are 24 feet on
center.See Figure 1 for the blast loading for the “medium” risk
scenario. Determine the blast load to be applied to the column.
Model the column as an equivalent elastic system and calculate one
second of the displacement response time history. Determine the
maximum displacement and bending moment.
