Bending Strength of Vertically Glued Laminated Beams with One to Five Plies.

Abstract

Properties of vertically laminated beams were studied to determine the effects of number and quality of component laminations on structural performance. Deterministic and probabilistic analyses were both used to show how performance varies with number and quality of laminations and with assumed loading parameters. Increase in allowable stress with number of laminations, currently recognized as a constant adjustment for three or more laminations, was significant for two-lamination beams as well. This increase proved to be inversely related to lumber quality. Results will be helpful to organizations publishing engineering design stresses in establishing a more efficient design of vertically laminated beams. (Author)
