Abstract:

The objectives of the investigation were to design and model test a blast-resistant reinforced concrete slab system serving as the roof of a basement shelter area. The slab system was designed to offer sufficient radiation and blast protection to insure a survival probability for its occupants of 85 to 95 percent for a fa 15-psi airblast overpressure loading. Static and dynamic tests were conducted on two 14-scale models of a prototype shelter. The prototype shelter, as designed, has a reinforced concrete flat slab roof consisting of three 18-foot spans in each direction supported by four interior columns and by a continuous wall around the perimeter. The model included the perimeter walls and different panel configurations which would influence the load-carrying capacity of the prototype structure. The slab system was designed using the empirical method of the 1963 American Concrete Institute Code with modifications to account for the dynamic loading effects. Author
