    Stiffness of concrete deck slabs

    Allow my 2-cents in this. Ixx and Iyy are geometrically appropriate for beams, but for plates, the equivalent would be (width x thickness^3/12) for a slab. Plate theory expresses dimensions and loads in terms of per unit width (i.e., in-lb/in line moment), so the appropriate equivalent unit...
