| Summary: | A method has been developed for the design of reinforced concrete RC members when subjected to blast loadings based on
the nondimensional energy spectrum. Numerical analyzes showed good agreement between the approximate responses of RC members
designed to their respective levels of target response. This paper further verifies this method through the actual response of a RC column
and beam subjected an actual denotation of explosives at a short standoff. When subjected to blast loading from a short standoff distance,
the cantilever column behaved predominantly in direct shear. Thus, ways to mitigate the damage of a cantilever column should draw focus
on the robustness. The developed design procedure provides a feasible method for the blast resistant design of members, subjected to blast
loads at a short standoff distance. |
