Structural and Economic Benefits of Precast/Prestressed ...

precast/prestressed concrete can pro-vide. A pretensioned precast slab can be combined compositely with an in situ concrete topping to produce a slab that provides substantial savings in ma-terials over an equivalent conventional cast-in-place slab. Fig. 5(a) illustrates this advantage, based on shoring the precast slab at midspan before plac-
