RESUMO

Due to the importance of wood in construction and the concern about the environmental impact, engineers have worried about the rationalization of its use through the development of engineered products, seeking the improvement of the technical properties. In this study, the I-beams built with reforestation wood were used for concrete formwork purpose. Their mechanical properties and the connections between flanges and web used in its manufacture were evaluated by means of bending tests and shear in the glue line. These beams are commercially called H2O. The flanges were made from Pinus Oocarpa, the webs were made from laminated plywood, block plywood, and Pinus Oocarpa, and two types of adhesives were used: polyurethane and resorcinol-formaldehyde. The H2O beam configuration showed the best results compared to the minimum required by European standard EN 13377:2002 was with the flange made from lumber, glued with resorcinol-formaldehyde and the web of laminated plywood.
