Book excerpt: Oak Ridge National Laboratory field tests of expedient shelters during the past three years had resulted in the selection and development of six types of expedient shelters. These were demonstrated by construction exercises to be the most practical for average rural and small-town Americans to build in the principal environmental regions of the United States. Each type of shelter is designed to be built within 48 hours by average family groups of such Americans, using only widely available materials such as trees, to provide all members with high-protection-factor shelter. To evaluate the blast protection afforded by these six types of expedient shelters, they were blast tested as a part of Defense Nuclear Agency's Mixed Company Event, in the blast area of a 500-ton TNT detonation--equivalent in air blast effects to a 1.0-1.8 kiloton nuclear detonation. A total of twelve shelters, representing six expedient types, were subjected to blast effects at surface overpressures ranging from 29 to 3 pounds per square inch (psi). All except the two Door-Covered Trench Shelters were tested as closed shelters. Only one shelter was damaged: the Door-Covered Trench Shelter that was tested as an open shelter at 5 psi. The six types of shelters, tested at the following measured surface overpressures, were: (1) Two Small-Pole Shelters, at 29 psi; (2) Three Wire-Catenary-Roofed Shelters, at 29 psi and 13 psi; (3) One aboveground A-Frame Pole Shelter, at 17 psi; (k) One Shored-Trench Stoop-In Shelter, at 13 psi; (5) Two Log-Covered Trench Shelters, at 13 psi; (6) Two Door-Covered Trench Shelters, at 5 psi and 3 psi. Earth arching increased the strength of the shelters that had an adequate depth of earth cover relative to the roof span. A new design of quickly closable, expedient blast door was tested at 29, 17 and 13 psi surface overpressure ranges. Only the blast door at 17 psi was damaged, and even it remained intact and securely closed.

Available in PDF, EPUB and Kindle. Book excerpt: To determine the worst blast environments that eight types of expedient shelters can withstand, we subjected a total of 18 shelters to the 1-kiloton blast effects of Defense Nuclear Agency's DICE THROW main event. These expedient shelters included two Russian and two Chinese types. The best shelter tested was a Small-Pole Shelter that had a box-like room of Russian design with ORNL-designed expedient blast entries and blast doors added. It was undamaged at the 53-psi peak overpressure range; the pressure rise inside was only 1.5 psi. Expedient shelters of the types tested - especially if the ones with shored walls are equipped with blast doors - would afford better protection against the blast and fire effects of nuclear weapons and much better fallout protection than do all but a small fraction of existing buildings. Water storage pits lined with ordinary plastic trash bags were proven practical at up to 53 psi, as were triangular expedient blast doors made of poles.

Available in PDF, EPUB and Kindle. Book excerpt: A research program was conducted to evaluate the blast resistance of expedient fallout shelters designed for the civilian population in the event of a nuclear attack. As part of this research, model size shelters of six different designs were tested in a shock tunnel at average overpressure levels of 2.8, 4. 6, and 8.8 psi. Measurements of the external blast pressures and internal pressure leakage into the model shelters were made. The expedient shelters tested utilize, in general, shallow soil excavation, load-bearing members of timber or doors, and soil-covered roofs. Replica model sizes were selected so that the shock tunnel load durations were long enough to test in the quasi- static load realm. Some of the shelter designs survived at every overpressure level very well, while other tests items suffered structural failures in almost every case. This paper presents a brief description of the experiments, including some details of the shelters, of the model fabrication and pressure measurement system, and a summary of the results.

A Chinese ''Man'' Shelter, which skillfully uses very small poles to attain protective earth arching, survived 20 psi, undamaged. Two types of expedient shelters built of materials found in and around most American homes gave good protection at overpressures up to about 6 psi. Rug-Covered Trench Shelters were proved unsatisfactory. Water storage pits lined with ordinary plastic trash bags were proven practical at up to 53 psi, as were triangular expedient blast doors made of poles.

Available in PDF, EPUB and Kindle. Book excerpt: Simple shelters—that you can build quick Research was undertaken to evaluate how average citizens could create their own shelters in the case of a political crisis that could lead to a nuclear attack. It was known that at this time in the mid-1970s, after Civil Defense planning and spending had waned since the 1950’s-60’s, that both the Soviet Union and China had more preparations for their citizens in major urban areas. This book was created under the auspices of the U.S. ERDA, an agency created in 1974 when the Atomic Energy Commission was split into the Nuclear Regulatory Commission and the ERDA. This practical field research study became the original basis for Cresson Kearny’s more extensive book “Nuclear War Survival Skills”. What makes this report interesting and different is the wealth of extra info and photos that were NOT included in the book mentioned above. Simple shelters that can be built in 1 to 3 days and are outlined in this book are: - The Need for Improved Expedient Shelters - Door-Covered Trench Shelter - Stress test of Door-Covered Trench Shelter - Log-covered Trench Shelter - Occupancy test of Log-Covered Shelter - Above-Ground Door-Covered Shelter - Car-Over Trench Shelter - Large Log-Covered Trench Shelter - Overall conclusions and recommendations From the Introduction: "This report strongly indicates the practicality of tens of millions of Americans evacuating into rural areas and building and occupying high-protection-factor expedient shelters during an escalating international crisis. This concept was successfully tested by untrained families who built expedient shelters during winter in Colorado, summer in Utah, and spring in Florida. Their efforts are presented in this report primarily by the captioned photographs showing these typical American families evacuating their homes, driving to rural shelter-building sites, and then, with hand tools, constructing their own shelters. These average, mostly urban, American families were guided only by step-by-step, well-illustrated, written instructions given to them at the start of each experiment. Crisis conditions were simulated, and adequate motivation was provided by the promise of a cash bonus for completion of the shelter within 36 or 48 hours, depending on the difficulty of construction. All families, or groups of families, succeeded in winning the bonus, with one exception. The shelters built by the test families included the Door-Covered Trench Shelter, the Log-Covered Trench Shelter (which the building family occupied for 77 hours without emerging), and the Car-Over-Trench Shelter. Also, families are pictured while building four above-ground shelters designed for high-water-table or shallow-soil areas: the Above-Ground Door-Covered Shelter, the Crib-Walled Shelter, the Ridge-Pole Shelter, and the A-Frame Pole Shelter. These four above-ground shelters have protection factors (PF) in the range of 250 to 500. " Keywords: Civil defense,shelter,nuclear war,fallout,survival,improvised,radioactivity

Available in PDF, EPUB and Kindle. Book excerpt: A large number of experiments to test the response of various structures to nuclear effects were conducted at the Nevada and Pacific test sites during the 1950's. The results of the tests were published in Weapons Test (WT) Reports, but these received only limited distribution. A review of the reports reveals a wealth of information regarding blast shelters designed to resist the initial effects of nuclear explosions. This information is presented in the report. The summaries were prepared to make the results of applicable field experiments available to a larger professional audience with the practicing engineer specifically in mind. In general, the order of presentation follows the chronological order of the tests. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A 100-man Keyworker blast shelter was constructed and tested at the predicted 75-psi peak overpressure level in the MINOR SCALE Event in June 1985 at the White Sands Missile Range, New Mexico. The MINOR SCALE Event was a high-explosive test simulating the air-blast effects of an 8-KT nuclear weapon. The reinforced concrete shelter was designed by the US Army Engineer Division, Huntsville and the US Army Engineer Waterways Experiment Station under the sponsorship of the Federal Emergency Management Agency. The experiment was conducted to verify the structural design of the shelter. The full-scale structure was complete with air-handling equipment, bunks, and instrumented anthropomorphic mannequins. The survivability of mechanical air-moving equipment inside the shelter and occupant survivability were investigated. The structure experienced minor damage during the test. Permanent roof deflections were 1/8 inch or less. The mechanical equipment incurred no damage, and in-structure shock in the shelter was within acceptable limits for occupants. The test indicated that the shelter will safely protect personnel when subjected to the design peak overpressure of 50 psi from a 1-MT nuclear weapon. Recommendations resulting from the experiment included the retesting of the structure using a High-Explosive Simulation Technique (HEST) test to introduce significant damage to the shelter.
