Available in PDF, EPUB and Kindle. Book excerpt: To satisfy the increased demand for forest products, much of the future timber supply is expected to be derived from improved trees grown on managed plantations. This fast-grown resource will tend to be harvested in short-age rotations and will contain higher proportions of juvenile wood compared with wood in current harvests. As a result, current allowable properties may need to be reduced in the future. This report explores four options for monitoring the properties of fastgrown wood and briefly discusses the advantages and disadvantages of these approaches. The recommended multiple-stage sampling approach is illustrated in detail using simulated results based on the North American In-Grade test results for Southern Pine. Finally, the report presents details of a gbsreal worldgcs example of monitoring lumber properties currently being conducted by the Southern Pine Inspection Bureau.

Available in PDF, EPUB and Kindle. Book excerpt: Of the environmental factors which affect the mechanical properties of wood, one of the most important is moisture content. The development of standardized procedures for adjusting lumber strength for changes in moisture content is reviewed. Historically, the adjustment procedures for flexural properties in ASTM standard D 245-74 are shown to have been based on tests of lumber in structural sizes, with the magnitude of the adjustment being dependent upon the thickness and apparent strength of the piece. It is indicated that current adjustment procedures are based on mean strength properties that, when compared to tabulated average strength properties obtained from tests of full size lumber, were considered to be conservative for most species. A review of recent research results indicates that the magnitude of the seasoning adjustment for tensile and flexural strength of lumber is dependent upon the initial strength of the piece in the green condition. The need for an analytical model for describing the moisture content-strength relationship is stressed. Obstacles to the establishment of an effective model are discussed. Recommendations for future research in order to some of these obstacles are given. (Author).
