.... Results show the specific heat capacity of wood becomes nearly constant with increasing temperature once pyrolysis starts. Furthermore, for both species of woods, the heat capacity values level out at a higher temperature than leaves, with correspondingly higher final specific heat capacity values...

... A need exists to develop realistic surfaces, with differing degrees of surface roughness, to standardize methods for sampling and cleaning of environmental contaminants. This study reports on development and characterization of a novel means to create reproducible wood surfaces...

... This paper presents the measured convective mass transfer coefficients for humid air flowing above an initially dry gypsum and wood panel (equilibrium with 30 % RH air) in the transient moisture transfer (TMT) facility at the University of Saskatchewan. The convective coefficients are measured...

... content versus relative humidity at constant temperature. This paper discusses some confounding effects that we have observed while performing measurements on a number of common building materials. Materials studied included gypsum products, wood and wood products, and cementitious materials...

... Despite the importance of durable wood bonds, the factors that lead to durability are not well understood, and the internal forces exerted upon the bondline are often overlooked. Durability requires that the bonded assembly resist dimensional changes of wood with fluctuation of wood moisture...

... construction forms and methods are briefly discussed. Wood, our only basic renewable resource, has been an important part of man's built environment. For this to continue in the future, developments in timber engineering and related technologies should meet the needs and challenges demanded by building...

..., and 1985. The bitumen felt caused rotting of the shingles, and in 1972–95 a new wooden shingle roof and new wood panel were installed. The restoration principles considering authenticity were debated. The work was financed mainly by the state employment program. It was done by traditional methods by hand...

... of a variety of wood framing systems. The house remained virtually unchanged for almost 100 years until two early additions were demolished during extensive 1940 renovation work. Faulty initial structural design, istallation of contemporary conveniences, insect infestations, and poor 20 th century repair...

... Current research on wood reinforcement has focused on the use of fiber-reinforced plastic (FRP) strips or fabrics bonded to wood members. Although significant increases in stiffness and strength have been achieved by this reinforcing technique, there is a concern about the reliable performance...

... Wood-framed construction is an important part of the residential housing industry, and has been so for decades. While some of the waterproofing materials and technology available to the construction industry have improved dramatically in the past 10 years, the basic precepts and many...

... Secondary wood manufacturing covers a wide range of products from furniture, cabinets, doors and windows, to musical instruments. Many of these are now mass produced in sophisticated, high speed numerical controlled machines. The performance and the reliability of the tools are key...

... Many older and historic structures are built partially or entirely of wood, whose physical and mechanical properties are highly variable and characterized by a complex internal structure, which is porous, inhomogeneous, and anisotropic. The great variety of species, variability of the material...

... Many wood and wood-composite structural elements are exposed to fatigue loading situations in service. Because wood is composed of a complex cellulosic fiber-based structure at the microscopic level, fatigue cracking phenomena are not commonly observed. Fatigue-related failures can look just...

... A series of medium-scale smoke experiments were conducted at the University of California, Berkeley. Representative fuels, such as wood, asphalt roofing shingles, and liquid hydrocarbons, were burned as medium-scale fuel packages in the open, with no restriction on the ventilation. For some...

... A computer model for the heat release rate of wood is summarized and its input data requirements are specified. Some methods of obtaining these data are discussed. An apparatus for measuring the heat of combustion of the volatiles and the kinetic parameters for the mass loss rate of the various...

... A data base of steady-state thermal properties for 15 wood species representative of those used commercially in building construction has been developed from available test data. Selected mean values of conductivity, density, moisture content, and thermal resistance are tabulated...

... Currently used fire retardant coatings for wood products reduce flame spread; they are not designed specifically to provide fire resistance. Fire resistive coatings designed for steel and foam plastics generally are not recommended for wood. Small nonload-bearing fire resistance tests were...

... The use of fire resistive coatings in wood and steel construction is reviewed by the author, who visited the Union of Soviet Socialist Republics (USSR) in July 1981, as a member of the US-USSR Panel on Fire Protection. Included are English translations of two Soviet standards (GOST) for Fire...

... Results of test programs with short pile sections and small clear specimens are reviewed to evaluate the influence of imperfections and preservative treatment on the strength properties of timber piles. Reduction factors developed from this review, available information on natural wood strength...
