Abstract:

This report describes progress during the second years work on a Civil Defense program to provide FEMA with a range of damage functions and casualty functions to determine the survivability of people in various basement shelters. The characteristics of flat and two-way slab systems and the effects of code specified design procedures, engineering practice, and construction procedures were discussed. Non-upgraded two-way slabs are approximately twice as strong as the flat plate slabs. For upgraded shored systems, however, specific building characteristics are not important factors any shored slab, with standard reinforcing and dimensions, has about the same capacity as any other slab. A mathematical model for the fragility curve of slab systems was developed. Fatality curves have been developed for ceiling collapse and a variety of other casualty mechanismnuclear weapons effects with emphasis to date on non-upgraded shelters areas. This review of casualty producing mechanisms is continuing and all casualty curves should be considered as provisional.
