Resistência ao cisalhamento de ligações coladas de madeira

Abstract

The present work evaluates the shear strength at the glue line of glued wood joints made using the species Eucalyptus urograndis and Pinus sp. and vegetable oil based adhesive. The results obtained from the tests show that the variations in the concentrations of adhesive used in the execution of the joint, as well as the wood species adopted, did not lead to a significant difference in shear strength parallel to the wood fibers presented in the glued joints, occurring for the Eucalyptus urograndis wood, even a higher shear strength in the glued joint in relation to the solid piece of the same species. This confirms the advantages presented by the existing literature regarding the use of glued wood joints and it is expected that studies like this will encourage the use of this technology, and the development of others, in the execution of structural elements and other areas of civil construction.
