The finished product is subject to a classic strength assessment procedure known as visual grading. In this study, 484 specimens of No.2 2 inch by 8 inch (nominal) SYP dimensional lumber were visually assessed for strength reducing defects, visually graded by a certified lumber grader, and destructively tested. Destructive testing was performed in accordance with ASTM D4761-13 for modulus of rupture (MOR) and modulus of elasticity (MOE). These results were used to identify parameters which could be significant when developing a potential working stress-class system to improve the efficiency and yield of the specified grade. Six specific visual characteristics were identified that could predict a superior quality product when compared to the current strength and stiffness properties of No.2 2 by 8 lumber. </p> Rubin Shmulsky Dan Seale Dave Kretschmann MSSTATE 2016-04-18 text application/pdf http://sun.library.msstate.edu/ETD-db/theses/available/etd-03222016-175244/ http://sun.library.msstate.edu/ETD-db/theses/available/etd-03222016-175244/ en restricted I hereby certify that, if appropriate, I have obtained and attached hereto a written permission statement from the owner(s) of each third party copyrighted matter to be included in my thesis, Dissertation, or project report, allowing distribution as specified below.
