This document identifies the essential characteristics of ribbed floor elements. These elements are precast elements made of reinforced or prestressed normal weight or light weight concrete, used in floors or roofs. They consist of a top and/or bottom slab and one or more (usually two) ribs; transverse ribs may also be present. The concrete does not contain more than 1 % of homogeneously distributed organic material, by mass or by volume (whichever is the most onerous).
When used in roofs, these elements are used in the same way as for a floor, the difference being in the type of covering and the loads they support.
This document specifies procedures for assessment and verification of constancy (AVCP) of performance of characteristics of the ribbed floor elements as well as marking and labelling of these elements.
NOTE This document does not cover load-bearing capacity determined by testing.
