Book excerpt: This study involved the evaluation of ponderosa pine glulam made from lumber that was sawn from a small-diameter timber resource. Two different glulam beam depths were evaluated: 8 and 13 laminations. A comprehensive glulam test program was conducted to evaluate edgewise and flatwise bending, shear, and tensile strength. Beam deflection was measured and a variety of glulam MOE values were determined. The calculated design values for various mechanical properties of this new ponderosa pine glulam beam combination were compared to the published design values of the L3 glulam combination. Using mechanically graded lumber in the glulam combination resulted in a structural member that efficiently utilized this small-diameter ponderosa pine resource. The calculated design values of this new glulam combination are a significant improvement over the published design values of the all ponderosa pine L3-grade combination that is currently available in the standards.

Available in PDF, EPUB and Kindle. Book excerpt: In the United States, almost 300 million acres of forests are severely overcrowded with small-diameter, densely stocked trees. These forests need to be thinned to improve their health and reduce the risk of catastrophic wildfire. However, thinning is an expensive task, costing from $200 to $1,500 per acre. Traditionally, there has not been a market for this material once it has been thinned. Uses for small-diameter wood must be found and markets for the products created in order to offset the cost of thinning. For several years, the Forest Products Laboratory (FPL) has conducted cooperative studies with local communities and industry to improve the use of wood from small-diameter trees. One of the most common species in these stands is ponderosa pine. Preliminary testing on ponderosa pine lumber indicates that if mechanical grading technology is applied, this material could be used in higher valued structural applications such as glued-laminated timber (glulam).
