The two-way flexural behavior of steel-deck-reinforced concrete slabs is examined and the feasibility of considering two-way action in the design of such slabs is discussed. An elastically orthotropic finite element model with uniform thickness is developed which simulates the behavior of a structurally orthotropic steel-deck-reinforced concrete slab. The model development is based upon appropriate modifications to the elasticity constants and to the thickness of the plate bending element included in the SAP IV1 finite element program. The linear, elastic, uncracked behavior of a typical steel-deck-reinforced concrete slab is examined utilizing the elastically orthotropic model and, the resulting deflections and moments are observed to conform with theoretical results and with a more sophisticated structurally orthotropic model. The elastically orthotropic finite element model is also correlated with previously tested steel-deck-reinforced concrete slabs and the results predicted by a finite element analysis are found to conform with the actual test results in the uncracked region.
