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...

Streambed scour and redeposition behavior in streambed simulated culverts over an annual period

Creator:: Stewart, Anna
Abstract:: The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...

Hybridized framing to modify load paths and enhance wood shearwall performance

Creator:: Bultena, Sarah M.
Abstract:: Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...

Effects of pressure and deposit thickness on the stabilization rate of benthic marine sludge deposits

Creator:: Muellenhoff, W. P.
Abstract:: The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....

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...

Evaluation of straw wattle placement and surficial slope stability

Creator:: Rikli, Anthony M.
Abstract:: Straw wattles are common erosion control devices used to trap sediment. This thesis studies the relationship of straw wattles on slope stability through a case study demonstrating their use on steep slopes (1.5H:1V) for the US20 highway realignment project. Several surficial slope failures have occurred on these fill slopes, often...

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,...

An Efficient Workflow and Accuracy Assessment for ICESat-2 and Multispectral Imagery Fusion for Bathymetric Mapping

Creator:: Babbel, Benjamin J.
Abstract:: Interest in mapping bathymetry from multispectral satellite imagery has grown steadily since the 1970s. Notwithstanding the significant advancements made during this time, one limitation is that the group of algorithms collectively referred to as Satellite Derived Bathymetry (SDB) generally require “seed depths,” hindering their use for areas lacking reliable reference...

Radar and Optical Remote Sensing of Submesoscale Frontal Features

Creator:: Simpson, Alexandra J.
Abstract:: The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

New Techniques to Monitor and Characterize Landslide Behavior and Controls Using Digital Terrain Models

Creator:: Senogles, Andrew
Abstract:: Coastal landslides and erosion are major natural hazards resulting in unstable slopes, constituting immense challenges to modern infrastructure. Developing, maintaining, and performing risk assessments of infrastructure on, or close to, these hazards require a detailed understanding of the geophysical processes destabilizing the slope. These efforts start with the collection of...
