Summary
Although the glulam is a product of the nineteenth century, there are few industries in Brazil. The high cost of the structural elements of glulam is committed at the time, its competitiveness with full tropical sawn timber and reforestation. Being a tropical country, we recommend the use of wood treated to prevent termites attack. This study aims to evaluate the resistance of glulam beams before and after being subjected to chemical treatments with pressure using CCA (Copper Chrome Arsenic) and CCB (Copper Chrome Boron). To that end, we tested 54 glulam beams with nominal dimensions of 9 cm x 9 cm x 200 cm, with wood harvested from forest plantations. These beams were subjected to static bending tests, according to Brazilian standard NBR 8458:1984. After analyzing the experimental data it was concluded that the glulam beams produced from wood of Pinus oocarpa had the best results, taking into account the combination wood-adhesive-treatment, because the physical properties remained the same before and after chemical treatment in fullcell method.
