Abstract
Bending strength, was assessed in glued laminated beams made from local wood species bonded with phenol resorcinol formaldehyde, polyurethane and urea-formaldehyde adhesives. The 3- point loading was used as the basis of bending strength assessment along the directions parallel and perpendicular to the glue line. The load orientation parallel to the glue line offered higher bending strength. Furthermore, the characteristic values of bending strength obtained were 35.16 N/mm2, 40.79 N/mm2, 47.34 N/mm2, 60 N/mm2, and 67 N/mm2 for Afara, Akomu, Gmelina, Iroko, and Omocedar wood species. These values are similar to strength values given in EN 1194-1999 for glulam beams. Consequently, the findings of the study are beneficial to architects and structural engineers in exploring the dimensional, strength, and architectural flexibility glulam affords for both beam and column design and holds the potential for creating an industrial hub for enhancing the value chain around engineered wood and allied industries.
