Abstract

The objective of this work is to determine the structural performance of glued laminated timber walls using the Brazilian standard NBR 15575 (2013). Five walls with cross-section of 9 cm x 140 cm and height of 260 cm were made, 3 of these walls of Eucalyptus cloeziana and 2 of Eucalyptus grandis. The adhesive used was resorcinol formaldehyde resin base. A physical and mechanical characterization of the wood was performed before the tests. The walls were assembled from the union of 5 glued laminated timber beams of 52 cm in length. The union was made through the male-female system, using adhesive. Simple compression, soft body and hard body impact tests were performed, according to thespecifications of NBR 15575 (2013). The boundary conditions were fixed at both ends. The instrumentation consisted of load cell and 3 displacement transducers. The load application was monotonic until reaching maximum load. The results of the simple compression tests and the soft body and hard body impact tests indicate high structural performance of the glued laminated timber walls, and, therefore, meeting the specifications of NBR 15575 (2013).
