Problems of Wood-based I-beams Carrying Capacity

Nowadays, wood-based I-beams are becoming increasingly popular. They are used in the frame construction industry and traditional structures such as: ceiling girders, roof girders or walls poles. Their use is suitable in energy-saving buildings and passive houses. The paper deals with the results of laboratory tests of glued I-beams made of wood-based materials. The tested I-beam was created by connecting two shelves of structural wood and an OSB board. The I-beams were tested in an accredited laboratory in bending and shear. The statistically evaluated results of carrying capacity from the laboratory tests are compared with the results obtained from calculation according to current European standards.
