Wood materials and shearwalls of older light-frame residential structures

Creator:: Carroll, Cameron T.
Abstract:: Light-frame construction practices and materials have changed greatly over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...

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...

The mechanics of the Salt Range-Potwar Plateau, Pakistan : qualitative and quantitative aspects of a fold-and-thrust belt underlain by evaporites

Creator:: Juame, Steven C.
Abstract:: The collision of the Indian subcontinent with Asia beginning 40 million years ago produced the Himalayan orogenic belt, the largest continental collision belt active today. The foreland fold-and-thrust belt in northern Pakistan consists of the Salt Range-Potwar Plateau area. In this region the distance from the Main Boundary Thrust(MBT) to...

The influence of monovalent cations on tryptophanase and pyruvate kinase as studied by fluorescence, circular dichroism, and kinetic methods

Creator:: Leete, John Huntington
Abstract:: Two spectrally different species of holotryptophanase were obtained from fluorescence and circular dichroism measurements. One is predominant in solutions containing certain enzyme activating monovalent cations while the other predominates in solutions of various inhibiting monovalent cations. Relative magnitudes of the cation sensitive fluorescent intensity maxima or circular dichroism maxima are...

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...

The effects of nail bending-yield stress and biological deterioration on the cyclic performance of shearwalls

Creator:: Anderson, Erin N.
Abstract:: Key parts of the lateral force resisting system in wood-frame buildings are the shearwafls and the connections. The connections in wooden buildings are the primary source of ductility and energy dissipation; these are essential properties when buildings are exposed to lateral forces, such as wind and earthquakes. Shearwall design is...

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 development of the chlorinity-salinity concept in oceanography

Creator:: Wallace, William J.
Abstract:: This study traces the historical foundations of the concept of constant ionic proportionality and the equation (Salinity [S%₀] = 1.805 Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography since 1902 until 1969 and which is based upon this constancy, The notion that the constituents present in...

The Development of Astronomy in the United States Prior to 1900

Creator:: Harburg, William A.
Abstract:: From the earliest English colonization to the present day, there has been interest in astronomy in this country. The purpose of this thesis is to show how the science of astronomy developed in America from the earliest observations by educated colonists using imported instruments and publishing in European journals, to...

Submarine earthquakes, volcanic eruptions and ambient noise in the Northeast Pacific

Creator:: Haxel, Joseph H.
Abstract:: Passive hydrophone technologies and a variety of acoustic methods are applied in the deep-ocean and shallow water coastal environments of the northeast Pacific. A catalog derived from U.S. Navy regional hydrophone array recordings of acoustic T- phases from seafloor earthquakes is examined, describing space/time patterns through empirical orthogonal function analysis...
