Download or read book Dynamic Strength Study of Small Fixed edge Longitudinally Restrained Two way Reinforced Concrete Slabs written by Wayne M. Brown and published by . This book was released on 1973 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increases in ultimate strengths of 23.7 (Series I) and 24.6 (Series II) percent under dynamic loading were obtained. Theoretical slab strengths were determined. Modification of the equations used allowed good predictions of tensile membrane resistance of the static slabs. The equations were used to predict peak pressures sustained by the dynamic slabs.

This book was released on 1969 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two studies, one theoretical, the other experimental are reported. The strength and behavior of restrained reinforced concrete slabs were investigated under both static and dynamic loads. Nine 6-foot-square slabs were tested: six under uniform static pressure and three under long-duration dynamic loads. Steel reinforcement ranged from zero to 1.33 percent. The slabs failed initially in a flexural mode, followed by total collapse at a much greater deflection. The thinner slabs deflected more than 2.5 times their thickness under both types of loading. The theoretical study deals with a square slab, restrained against rotation and longitudinal movement at the edges. The study covers static resistance, failure criteria, size and extent of fragments, and design recommendations. An analytical method is developed to predict the static resistance, deflection, and longitudinal restraining thrust at ultimate failure. The resistance and behavior of longitudinally restrained square slabs are predictable, and if properly designed can resist dynamic loads effectively and more economically than those with no longitudinal edge restraint.

Download or read book Expedient Upgrading of Existing Structures for Fallout Protection written by William L. Huff and published by . This book was released on 1978 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted in support of the Defense Civil Preparedness Agency's (DCPA) Crisis Relocation Planning (CRP) program in which existing structures will be upgraded to provide fallout shelters for a relocated population. A demonstration test was conducted in which a residential dwelling was upgraded by placing soil against the walls and on the roof of the structure. The shelter was large enough to house 80 people. Upgrading was accomplished partially by hand labor and machinery. The test showed that a conventional structure could be upgraded and that the shelter occupants using tools and materials found in most homes could if necessary upgrade their shelter during the expected 2- or 3-day period of crisis relocation preceding a nuclear attack.

This book was released on 1975 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the study reported herein was to determine the response, up to collapse, of a conventional floor and framing system typical of the systems which would be located over a basement fallout shelter in a steel frame building. Static and dynamic tests were conducted on two 1/4.5-scale models of the basement shelter area from a multistory steel frame prototype structure designed for this study.

Available in PDF, EPUB and Kindle. Book excerpt: This report contains information on protective capabilities of a variety of different personnel shelters against prompt effects of nuclear weapons. This information was collected from previous studies performed for DCPA in this subject area. Protective capabilities are expressed in terms of 'people survivability functions' which relate the probability of survival (or percent survivors) to the free field overpressure at the shelter site. Respective shelters are described in terms of their geometry and material properties. The following shelter categories are included. (1) Existing Engineered Buildings (Upper Stories and Basements), (2) Designed Basements, (3) Single-Purpose Shelters, (4) Dual-Purpose Shelters, (5) Expedient and Special Purpose Shelters and (6) Expediently Upgraded Shelters.
