    beams, columns - Light composite wood-based beams and columns

I-beams or double T-profiles are wood-based composite elements, consisting of 2 flanges and a intermediate web which are glued together. They are intended to be used as loadbearing parts of building constructions, the use is limited to service class 1 and 2 (according to ÖNORM EN 1995-1-1 (Eurocode 5). The top and bottom flanges are mainly made of strength graded structural timber (according to ÖNORM EN 338, ÖNORM EN 14081), glued laminated timber (according to ÖNORM EN 14080) or laminated veneer lumber (LVL) (according to ÖNORM EN 14374). The webs are mainly made of oriented strand boards (OSB/3 or OSB/4) in accordance with ÖNORM EN 300 or hardboards according to ÖNORM EN 622-2. Glued joints of flanges to webs or webs to webs have to meet the requirements of ÖNORM EN 301 or ÖNORM EN 15425. The elements are used as columns, floor and roof beams. Materials, dimensions and mechanical properties of the product are manufacturer-related and are given in the European technical approval (ETA) of the manufacturer. The reaction to fire is classified in accordance with the used materials, e. g. fire class D/ smoke production s2/ flaming droplets d0. I-profiles oder double T-profiles require a certificate of conformity in accordance with European technical approval (according to ETAG 011 "Light composite wood-based beams and columns") and the associated CE-certification. Additional european or national laws/regulations/implementations may apply.
