Design analysis using function-based failure propagation in failed system states

Creator:: Jensen, David Charles
Abstract:: For safety critical complex systems, reliability and risk analysis are important design steps. Implementing these analyzes early in the design stage can reduce costs associated with redesign and provide important information on design viability. In the past several years, various research methods have been presented in the design community to...

Utilization of low-value lumber from small-diameter logs harvested in Pacific Northwest forest restoration programs in hybrid cross laminated timber (CLT) core layers : a market response

Creator:: Lawrence, Brent
Abstract:: The United States spends about $2 billion each year fighting wildfires. While it is a costly operation, mechanized thinning of dense federal forests is one preventative strategy that generates high volumes of small logs. These small logs are often used for wood chips, pulp, or biomass because of the high...

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...

Offshore renewable energy : an exploration of techno-economic feasibility and reliability through a computational optimization perspective

Creator:: Clark, Caitlyn E.
Abstract:: Offshore renewable energy (ORE) has the potential to be a significant source of future global electricity production, reduce carbon emissions, decrease dependence on energy importation, and stimulate economic growth in coastal and remote areas. The availability and abundance of ORE, paired with growing coastal population centers, position offshore wind, wave,...

Strain distribution in OSB and GWB in wood frame shear walls

Creator:: Sinha, Arijit
Abstract:: The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...

A Methodological Approach for Structural Health Monitoring of Mass-Timber Buildings Under Construction

Creator:: Baas, Esther J.
Abstract:: As mass-timber building construction rises around the globe, there exists the need to verify the long-term, in-situ behavior and performance of these structural systems. Structural health monitoring (SHM), generally defined as a damage detection strategy consisting of a network of sensors, a data acquisition system, and algorithms for data analysis,...

In-plane Creep Behavior of Cross-laminated Timber and Mass Plywood Panels: A Methodology to Evaluate the Long-term Performance of Post-Tensioned Mass Timber Walls

Creator:: Longman, Ryan P.
Abstract:: Post-tensioned (PT) self-centering shear walls were designed to reduce structural damage from seismic activity. However, these lateral force resistant systems experience post-tension loss negatively affecting the re-centering capability due to delayed deformations experienced by engineered wood products over time. The long-term mechanical response of mass-timber panels to in-plane PT loads...

Fluorescence Spectrometry to Quantify Percent Wood Failure in Adhesive Bonds

Creator:: Rueppel, Talbot B.
Abstract:: Structural engineered wood manufacturers need a quantitative measurement technique to determine the ratio of wood to adhesive failure in their shear specimens. Visual estimation of percent wood failure has long stood as an extremely subjective quality control approach according to ASTM D5266 – Standard Practice for Estimating the Percentage of...
Resource Type:: Masters Thesis
Full Text:: rebuttal to a presupposition, when in fact, no single theory of adhesion fully explains the phenomenon on

Process modeling the physician-patient encounter

Creator:: Tong, Xiaomin
Abstract:: The objective of this research was to provide a definitive description of the processes within the physician-patient encounter in an office setting. This description would take the form of a formal process model of the encounter in a provider's office setting, as this represents the most common situation during patient...

Performance characterization of an integrated microscale hydrogen combustor recuperator and oil heat exchanger

Creator:: Haley, David B. (David Brien)
Abstract:: Experiments on a novel, microscale hydrogen combustor heat exchanger (µCHX) are presented in this thesis. The µCHX has been designed to efficiently transfer thermal energy to a heat transfer fluid for use in desorption of hydrogen from a metal hydride storage system of a hydrogen-powered fuel cell vehicle. The experimental...
