COMPARISON TEST OF REINFORCING STEELS,
Abstract
The project was planned to determine the relative merits of rail- and intermediate-grade steel as reinforcement in concrete slabs subjected to blast loading. Slab pairs were placed at ground level over deflection chambers and loaded with the incident pressure pulse from a nuclear device. Two station locations were chosed so that the loadings were approximately 7 and 5 psi peak overpressure. The slabs comprising each pair were identical except for the grade of reinforcement in each. Slab strengths were varied, and two test stations were used to increase the probability of realizing the response necessary to emphasize the advantages of each steel grade. Measurements were made of the dynamic midspan slab deflections and the transient loading pulse. A through posttest survey was conducted to determine the severity of the resulting damage to the concrete slabs. Test results indicated that the desired range of slab behavior was achieved. In all cases the rail slabs displayed the more desirable response. However, limitations of this experiment, due to loading and structural conditions, must be considered before this conclusion can be generalized. (Author)
