OPTIMUM REINFORCEMENT IN SPANDREL SUPPORTED SLABS

Research is reported which attempted to accomplish the following: develop a generalized yield analysis for a rectangular slab panel with any arbitrary edge conditions consistent with the torsional capacities of the edge beams; optimize the reinforcement in a rectangular panel with generalized edge conditions; and optimize the reinforcement in a system comprising the rectangular panel and the edge beams along two adjacent edges. It was found possible to determine the load-carrying capacity of a reinforced concrete slab panel while taking into account the actual torsional capacities of the supporting edge beams. For a given slab panel, the load-carrying capacity increases monotonically with increasing edge restraints, or, for a given load capacity, the reinforcement decreases continuously with increasing edge restraints. For the optimization of the system reinforcement, spandrel beams may have minimum torsional reinforcement consistent with adequate ductility.
