Upgrading basements for combined nuclear weapons effects: predesigned expedient options II. Final technical report
This report covers the results of the latest phase of a 3-phase project, with the overall objective of developing a set of expedient and engineered techniques, for upgrading the air blast and related effects resistance potential of basements in existing buildings. The purpose of upgrading such basement spaces is to provide shelter when needed by persons in: host areas where the bulk of the population is expected to be during an attack, that are located at and beyond the 2-psi air blast range, using selected target aiming points and Mt-range bursts; and, risk areas, where shelter is needed that is within 15-minutes travel time of each key worker's place of work and provides potential shelter for 30- to 50-psi air blast ranges, in terms of peak free field overpressure. Chapters of this report's main text are devoted to discussions of: background; general principles applicable to upgrading basements; closures for all basement shelter openings/apertures, in terms of principles for providing them; needs to be met in strengthening the structure over shelter candidate basements; some techniques and materials than can be used for such structure strengthening; and, shelters for key workers. In general, the main text of this report is intended for the artisan, the appendices having the more extensive, technical data and discussions. The titles of the appendices are: Blast-Resistant Design/Analysis General Approach; Plywood Stressed-Skip Panels (Two-Sided Only) as Closures - Design and Fabrication; Plywood Stressed-Skin Panels (Two-Sided) as Beam-Columns; Plywood Use for Closures - Design; Wood Beam and Column Design - Simply Supported; Home Basements Upgrading in Host Areas; Blast-Resistant Design/Analysis of Steel Members; and, Structural Steel Local Availability and Use for Blast Shelter Upgrading.
