摘要

The Glued Laminated Timber is an engineered product that requires precision manufacturing in all its stages. The finished product can only be tested in laboratory conditions; however it is necessary to quality control in their production to ensure that the properties of the Glulam are appropriate to the product specified requirements in accordance with specified for the product in accordance with the standards. This paper aims is to evaluate the proposed trials conducted with combinations of three Brazilian reforestation species, two adhesive and three types of treatment, used in of Research and Development CPFL / EESC "PD220-07 - HEAD OF SERIES CROSSHEAD.
