This design guide presents state-of-the-art practices in voided slab construction. The concept centers on removing concrete mass from the areas of the slab where it is not structurally efficient; thus reducing the dead load by as much as 35%. This floor system allows for large, clear spans and efficient overall slab thicknesses. Innovative structural slab construction practices have taken the efficiency of traditional slab systems to new heights.
An addendum to the Design Guide for Voided Concrete Slabs was released in mid-2019.
