Technical Note ETN-B-4-17
14 pp.; 2017
Flat plate voided concrete slab systems, which have been used for many years in Europe and other parts of the world, are becoming increasingly popular in the U.S. because of many inherent benefits. Such benefits include reduced weight, which results in smaller seismic forces and larger allowable superimposed loads for given span lengths; economical longer spans without beams; reduced floor-to-floor heights; accelerated construction schedules; and inherent fire resistance that meets the fire-rating requirements in the International Building Code (IBC). Updated to include information about fire testing.
CRSI routinely receives inquiries concerning various aspects on the design and construction of flat plate voided concrete slab systems. This Technical Note contains a collection of typical questions, which mainly came from design professionals, including structural engineers, architects, field inspectors, code enforcement officials, and contractors.
