Development of Damage and Casualty Functions for Basement Shelters
This report describes progress during the second year's work on a Civil Defense program to provide FEMA with a range of damage functions and casualty functions to determine the survivability fo 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 mechanism(nuclear 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. (Author)
