Creator:: Beuter, John H., Arney, James Douglas, 1941-, and Oregon State University. Forest Research Laboratory
Abstract:: Considerable interest has arisen in the relation between timber-selling procedures and the accomplishment of timber-selling objectives on public lands in the West. Procedures of public agencies for measuring and paying for timber by log scale or by lump sum have attracted special attention. There are significant differences in the two...

Abstract:: Moisture content and shrinkage were determined on specimens equilibrated at two conditions for equilibrium moisture content (EMC) at room temperature after the specimens had been dried under a variety of constant temperatures with constant EMC's. Moisture content at room temperature equilibrium was less for specimens dried at high temperature than...

Creator:: Kozlik, Charles J. and Oregon State University. Forest Research Laboratory
Abstract:: To test the effects of kiln-drying on strength properties of Douglas fir and western hemlock, temperatures to 230 F, conditions for equilibrium moisture contents of 6 percent and 12 percent, and prolonged heating were investigated. Prolonged heating and choice of conditions for 6 percent or 12 percent equilibrium moisture content...

Creator:: Johnson, James W. and Oregon State University. Forest Research Laboratory
Abstract:: Joints were fabricated from different combinations of untreated and fire-retardant- treated (FRT) Douglas-fir dimension lumber and 3/8-inch plywood. Eight types of fasteners and three fire-retardant treatments were tested. Joint specimens were exposed 2 and 7 years in cold, standard, and warm-humid conditions, then tested in lateral bearing. Best overall performance...

Abstract:: Eight series of untreated posts (including 5 series of steel), 22 series of nonpressure-treated posts, and 13 series of pressure-treated posts remain in test. Series in which all posts have failed now number 36 for untreated and 29 for nonpressure-treated. Causes of failures since 1949 were: fungi, 75 percent of...

Creator:: Kellogg, L. D. (Loren D.) and Oregon State University. Forest Research Laboratory
Abstract:: The Forest Engineering Department, Oregon State University, has evaluated several systems for thinning young timber stands on steep terrain. Stands averaged 35 to 40 years old and 25.4 to 35.6 cm (10-14 in.) dbh. Approximately 40 percent of the stems per hectare were removed in the thinning operations. This paper...
