Abstract:Outlines the problems involved in the structural design of two types of bomb-resistant shelters and emphasizes the inadvisability of any large program of shelter construction in the United States. A shelter to resist the direct hit of a IOOO-lb heavy case bomb uses a roof slab I I ft 3 in. thick, sidewalls 6 ft thick above ground and 9 ft thick below, and a base 5 ft thick. - ~_._ - A surface shelter to resist blast and splinters, from a IOOO-lb bomb exploding 25 ft away, employs l5-in. sidewalls and an 8-in. roof. The author closes with a plea and a suggestion for better outside walls for future buildings.
