The stress-strain relationships in wood and fiber-reinforced plastic laminae of reinforced glued-laminated wood beams

Creator:: Tingley, Dan A., (Daniel Arthur), 1954-
Abstract:: The reinforcement of wood and wood composite structural products to improve their mechanical properties has been in practice for many years. Recently, the use of high-strength fiber-reinforced plastic (FRP) as a reinforcement in such applications has been commercialized. The reinforcement is manufactured using a standard pultrusion process or alternatively a...

Assessing biaxial strength characteristics of wood-based structural panels

Creator:: Cheng, Ping, 1960-
Abstract:: Biaxial strength characteristics of wood-based structural panels were evaluated by using analytical and experimental methods. Cruciform plywood specimens were tested under biaxial tensile-tensile, compressive-compressive loadings in a symmetrically-jointed- arm test fixture, which was mounted on a universal testing machine. Performance of the test fixture was also evaluated during the tests....

Structural reliability of light-frame wood systems with composite action and load sharing

Creator:: Srikanth, Tarimala S.
Abstract:: In a majority of light-frame wood buildings, studs and joists are the basic structural components in walls and floors. The walls act as bending and compressive panels and transmit lateral wind and gravity loads to the foundation. Joists are used in floor systems, and together with the sheathing member act...

The effect of biological deterioration on the performance of nailed oriented strand board sheathing to Douglas-fir framing member connections

Creator:: Kent, Scott M.
Abstract:: Service life prediction models for light-framed wood structures require an extensive quantity of empirical data on deterioration pathologies for the numerous structural components, as well as mechanistic approaches to determine their capacity at various levels of deterioration. The data and models presented in this study satisfy a portion of the...

The effects of supercritical CO₂ on the bending properties and treatment defects of four refractory wood species

Creator:: Anderson, Matthew E.
Abstract:: It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood species may be an attractive alternative to conventional liquid carriers. While SCF impregnation has many potential advantages, some wood species...

Ionizing radiation and its chemical effects : a historical study of chemical dosimetry (1902-1962)

Creator:: Chorzempa, Mary André, Sister
Abstract:: Chemical dosimetry developed in response to needs created by developments in the field of high-energy radiation. Shortly after the discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious effects of ionizing radiation were recognized. To guard against the injurious effects of radiation in medical application, dose-measuring methods...

Self-evaluation of secondary school health teachers as compared to classroom student evaluation of the same teachers

Creator:: Brock, Michael S.
Abstract:: Sixteen secondary school health teachers evaluated their own course teaching performance. Students in each of these courses evaluated the same teacher and the results were compared. An adapted version of a teacher rating form developed by the School of Agriculture, Oregon State University, was used by all study participants. Teacher...

Forage intake and related performance criteria of spring and fall calving cow-calf pairs on summer range

Creator:: Kartchner, Rex John
Abstract:: Three studies during three consecutive summers were conducted at the Squaw Butte Experiment Station to estimate relative and quantitative forage intake of spring and fall calving cow-calf pairs on summer range. In a drylot study (experiment 1) individual animal consumption of fescue or meadow hay cut at 2- to 10-day...

Comparison of Vermont and Oregon statutory land surveyor laws

Creator:: Norton, Robert Leon
Abstract:: Land use planning, zoning, and subdivisions are integrally tied to the land resource. The need for a land surveyor and for statutes which govern his operation when working in these areas is stressed. A brief history of Vermont and Oregon, illustrating the role of land surveys on settlement, is given....

Least squares adjustment computer programs for horizontal and vertical positions

Creator:: Shrestha, Ramesh Lal
Abstract:: The application of the least squares adjustment techniques to the area of surveying has been considered and two computer programs called HCONTRL and VCONTRL are developed for horizontal and vertical control respectively. The principle of least squares is discussed in chapter II. The observation and condition equations are compared and...
