Thermal characteristics of thick red oak flakeboard by Roger H White( Book )
4 editions published in 1981 in English and held by 82 libraries worldwide
As part of a cooperative project between Prudue University and the U.S. Forest Products Laboratory, 1-3/16-inch-thick red oak structural flakeboard was tested for fire penetration, flame spread, and thermal resistance. The small-scale testing indicated satisfactory thermal characteristics for a wood- based product. Fire penetration performance exceeded that of a 1-1/8-inch-thick plywood accepted as roof decking in heavy timber construction. Flame-spread performance met the class C criteria of 200 or less. Thermal resistance was consistent with suggested insulative design values for particleboard. (Author)
Reliability analysis of fire-exposed light-frame wood floor assemblies by Frank E Woeste( Book )
3 editions published between 1980 and 1981 in English and held by 80 libraries worldwide
A reliability analysis using second-moment approximations is conducted on two types of fire-exposed, unprotected wood floors--conventional wood joist and floor-truss assemblies. A methodology is illustrated by which the probability of structural failure of a wood floor assembly can be evaluated. This probability, with the probabilities of failure of other system components, can be used in a systematic analysis that apparently is a viable approach to realistic analysis of building fire safety. The use of reliability analysis to compare relative fire safety of different floor components is demonstrated. A procedure for introducing new components into the market, based on a concept of an equal safety index calculated for a component with a proven inservice record, is discussed. (Author)

Smoldering wave-front velocity in fiberboard by John J Brenden( Book )
4 editions published in 1980 in English and held by 72 libraries worldwide
Fiberboard is used in large quantities for use in a broad spectrum of housing and building applications, one of which is sound-deadening board. As a result of reports documenting fire experiences with sound-deadening board, research was undertaken toward reducing or eliminating smoldering tendencies of fiberboard products. This report reviews previous work and reports on a test method to reproducibly measure smoldering wave-front velocity. (Author)

Hardwood Press-Lam crossties : processing and performance by John L Tschernitz( Book )
1 edition published in 1979 in English and held by 26 libraries worldwide
Crossties were made by the Press-Lam process, in which logs are peeled into veneers, dried, and glued into billets in a continuous procedure. Billets were made from 8.5-foot-long veneers and from 4-foot-long veneers, cut into final product dimensions, and treated with preservative. In laboratory tests, bending strength and stiffness of the Press-Lam ties were found to exceed those of solid-sawn red oak crossties; shear strength was only adequate. Tie wear tests showed low surface wear for laminated ties, comparable to the performance of solid specimens. Results of spike driving tests, however, indicated problems in some species. All Press-Lam ties met the performance criteria in the cyclic delamination tests, and, in lateral resistance tests, Press-Lam ties were not significantly different from solid-sawn ties. Volume yields are discussed and cost estimates are provided for use in calculating total tie costs for specific cases
Effect of panel thickness and noncombustible inserts on surface flammability of plywood by Erwin L Schaffer( Book )
2 editions published in 1967 in English and held by 22 libraries worldwide
Douglas-fir plywood in 1/4- to 1-inch thicknesses was evaluated for flame-spread resistance in the 8-foot tunnel furnace test, corner-wall test, and mild Schlyter test. Under these methods no signficant effect on flame-spread resistance was obtained by varying panel thickness. Work with noncombustible inserts showed that 1/32-inch asbestos or aluminum sheets employed with thin face veneers in panel constructions could significantly reduce surface flammability. (Author)
Charring rate of selected woods--transverse to grain by Erwin L Schaffer( Book )
2 editions published in 1967 in English and held by 20 libraries worldwide
A study was designed to determine the charring rates for wood normal to the grain, and to evaluate the effect of fire intensity, species, specific gravity, moisture content, and annual ring orientation on these rates. Other material variables studied were the springwood to summerwood ratio and volatile extractive content. The effect of variation in moisture permeability, however, was not evaluated. Laminated wood slabs, 3 inches thick, of Douglas-fir, southern pine, and white oak were vertically exposed to fire on one surface. The rate of char development was constant when the specimens were exposed to uniformly increasing fire temperatures; charring rates at three constant fire exposure temperatures were described by a pseudo-first-order reaction equation with an Arrhenius temperature-dependent rate constant. Rates of char development in each species were related to the specific gravity and moisture content of the wood. The other material characteristics considered were directly related to specific gravity and moisture content or had no significant effect on the charring rate. (Author)

Determination of temperature distribution in wood with variable surface temperature by numerical integration of Duhamel's integral by Fred Rattner( Book )
1 edition published in 1967 in English and held by 6 libraries worldwide
A numerical method is developed to determine the temperature distribution in homogeneous semi-infinite or thick-walled solids when the temperature of one surface varies with time. A computer program is given in 'FORTRAN' language for the determination of the temperature distribution in the solid and illustratively applied to wood that is subjected to standard fire conditions (ASTM E-119) at the surface. The results are presented graphically. It appears that the method developed can be applied with confidence to surface time-temperature functions of other materials. (Author)
