A shipment of 5,591 board feet of dense select structural southern pine, graded and inspected to conform to standard grading rules for southern pine lumber, was carefully investigated in order to determine (1) whether the lumber is within grade limitations, (2) what are the variations in and ranges of its physical and mechanical properties, and (3) whether it fulfills anticipations of design specifications.
Within its limitations, the study indicates that the investigated lumber fulfills the expectations of the National Design Specification despite the fact that some of the planks are found below grade according to the standard grading rules. Hence, those recommendations of the National Design Specification subjected to investigation are substantiated by laboratory test data on a commercially stress-graded shipment of southern pine lumber. / Master of Science
