Abstract:

Both conventional and nuclear weapons generate airblast loads of sufficient magnitude that structure survival at acceptable cost favors below grade construction. The design of shallow-buried underground rectangular structures has evolved from simplified analytical procedures which ignore the beneficial effects of soil-structure interaction. This paper presents design procedures based on recent research which results in much more economical structures.
