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 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...

Evaluation of the torsion test as a method to determine the shear strength of structural composite lumber

Creator:: Siller, Tobias Stefan
Abstract:: Torsion test was evaluated as a method to determine the shear strength parallel to grain of full-size structural composite lumber (SCL). Experimental results of eighty-five rectangular (44 x 140 mm²) specimens were verified by finite element analysis. Laminated strand lumber (LSL), laminated veneer lumber (LVL) and parallel strand lumber (PSL)...

Permanent deformation characteristics of dense-graded mixes using asphalt pavement analyzer

Creator:: Sandoval-Gil, Jesus A.
Abstract:: The Asphalt Pavement Analyzer (APA) device was used to characterize the impact of various mix factors on the development of permanent deformation in dense-graded mixes given a standard compactive effort. Factors included two aggregate sizes, three VMA levels, two fines contents, three binder contents and four binder types. All specimens...

Development and characterization of novel hydrogels for nucleus pulposus replacement

Creator:: Bader, Rebecca A.
Abstract:: Hydrogels have been proposed as candidates for nucleus pulposus replacement due to their similarity in mechanical behavior to the native tissue when subjected to transient or static loading; however, given the viscoelastic nature of soft biological tissues, the lack of dynamic testing is a significant inadequacy in the studies performed...

Quantification of total and plastic 3D strain fields within micro-damaged polyurethane foam

Creator:: Sutton, Matthew T.
Abstract:: Local material damage that occurs within cellular solids, such as polymer foams and trabecular bone, and precedes local fractures of the cell struts or walls is called micro-damage. The accumulation of micro-damage within cellular solids is often undesirable, although it is thought to be vital to the development and health...

Failure analysis of pre-notched composite laminated plates under four-point bending conditions

Creator:: Arias Gonzales, Sergio
Abstract:: Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...

Copper compounds for durable composites : effects on material properties

Creator:: Vidrine, Cheney L.
Abstract:: The effects of incorporation of selected biocides on physical and mechanical properties of aspen strandboard were assessed using five copper-based preservatives or zinc borate at three retention levels. Tebuconazole or 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (DCOI) were added as co-biocides to selective copper-based treatments. Mold box tests showed that only panels treated with DCOI...

In vivo assessment of nanomaterial-induced toxicity using embryonic zebrafish

Creator:: Usenko, Crystal Y.
Abstract:: Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...

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...
