Dynamic Strength Study of Small, Fixed-edge, Longitudinally Restrained Two-way Reinforced Concrete Slabs

📖 The Scoop

The study is one phase of an effort to develop criteria that will be helpful in evaluating or predicting the airblast load-carrying capacity of conventional floor slabs in existing Defense Civil Preparedness Agency approved shelters. The general objective of this study was to investigate the static and dynamic behavior of small, fixed-edge, longitudinally restrained, two-way reinforced concrete slabs. Twelve tests, four static and eight dynamic, were conducted on slabs with a clear span of 29 inches and a thickness of 0.89 inch. Two series of slabs corresponding to two different percentages of steel reinforcement (0.78 and 1.17 percent) were used. The slabs were subjected to uniformly distributed static loads up to 36.5 psi using water pressure and to dynamic airblast overpressures ranging from 26.5 to 56.8 psi using explosives. Measurements of pressure, deflection, and reinforcement strains were made, and results are presented. (Modified author abstract).
