Elastic behavior and ultimate strength of a continuous concrete slab prestressed in two directions were investigated. The slab, consisting of four panels, was supported at nine points and simulated a flat slab. Prestressing was accomplished by means of unbonded post-tensioned cables. Experimental values for moments, deflections, and reactions were compared with theoretical values’obtained by the elastic plate theory and by approximate theories used in present design methods.
