Mechanical Properties of Visually Graded Lumber. Volume 1. A Summary,


PB88159389

Publication Date 1987
Personal Author Green, D. W.; Evans, J. W.
Page Count 83
Abstract The document presents tables that summarize the data obtained on the mechanical properties of 2-inch dimension lumber sampled in the in-Grade testing program conducted in the United States. The tables summarize the data for strength in bending, tension parallel to the grain, and compression parallel to the grain and flexural modulus of elasticity. Flexural stiffness, moment capacity and tensile load capacity are also presented. Summaries are provided for these properties after adjustment to 73 degrees F and moisture contents of 12 percent (assumed 15 percent maximum), 15 percent (assumed 19 percent maximum), and 23 percent (assumed green value). Summaries include both parametric (two- and three-parameter Weibull, normal, and lognormal) and nonparametric estimates.
