Asnjë informacion i shtuar.

This European Standard deals with the requirements, the basic performance criteria and evaluation of conformity for precast beams made of reinforced or prestressed normal or lightweight concrete according to EN 1992-1-1:2004, with or without clay shell, used in conjunction with blocks in compliance with prEN 15037-2 or prEN 15037-3 or prEN 15037-4 or prEN 15037-5, with or without cast in-situ concrete for the construction of beam-and-block floor and roof systems. Examples of typology of floor and roof systems are given in Annex B. It is essential that the total depth of the beam be comprised between 60 mm and 300 mm and the beams be at centres of not more than 1,00 m. For higher depth, it is essential that the precast concrete beams be in compliance with EN 13225. The products covered by this standard are intended to be used as structural floor and roof systems, including parking areas for light vehicles corresponding to traffic category F of EN 1991-1-1:2002, which are not subjected to fatigue loading. The products may be used in seismic areas provided they fulfil the requirements specific to this use.
