Description: A summary of modulus of elasticity (MOE) and knot data is presented for grades of lumber commonly used to manufacture glued-laminated (glulam) timber by the laminating Industry. Tabulated values represent 30 different studies covering a time span of over 16 years. Statistical estimates of average and near-maximum knot sizes as well as mean and coefficient of variation for MOE are given. Modulus of elasticity values are compared with those published for design. Results will be helpful to organizations preparing and evaluating specifications for glulam timber.
Keywords: Elasticity, knots, glulam timbers, modulus of elasticity, laminated wood, specifications, surveys, lumber, moisture content, specific gravity, strength of wood
