A Summary of Modulus of Elasticity and Knot Size Surveys for Laminating Grades of Lumber.

reportActive / Technical Report | Accession Number: ADA106561 | Open PDF

Abstract:

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.
