Abstract:
Voided slabs, using voids formed by permanent fillers or removable forms, have been used in reinforced concrete floor systems for more than 100 years. The concept is simple: remove concrete mass from areas in the slab where it’s not needed to resist load. As a result of the reduced dead load, voided slabs can span further than their solid counterparts. This article provides a partial review of some early and contemporary systems and concludes with a discussion of a relatively new advancement.
