Nonlinear dynamic analysis of heavy timber frame structures including passive damping devices

Creator:: Eiden, Claudia M. T.
Abstract:: Engineering analysis of heavy timber structures under dynamic loads is generally lacking. Some literature suggests that heavy timber structures are stiffer than expected, but popular engineering opinion is to the contrary. In addition, prior research has shown that passive friction dampers can be used in timber structures for the intended...

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 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...

Slotted-bolted friction damper as a seismic energy dissipator in a braced timber frame

Creator:: Tjahyadi, Alfred
Abstract:: Friction dampers have been used successfully to dissipate seismic energy in steel and concrete structures. The application is new to timber structures. The objectives of this research were to design a slotted bolted connection (SBC) and evaluate its potential as a passive energy damper in timber brace. The research was...

Developing an analysis framework to compare commuter rail service and bus service in the Mid-Willamette Valley in Oregon

Creator:: Roholt, Ian M.
Abstract:: This thesis develops a framework for analyzing the application of commuter rail and bus services between several small urban centers to enhance overall connectivity. The study includes analyzing specific performance criteria for commuter rail service and express bus service based on data from existing systems around the U.S. The study...

Assessing Seismic Rockfall Impacts on Mobility in Transportation Corridors

Creator:: Holtan, Katherine
Abstract:: The climate and geologic conditions of the Pacific Northwest leaves its roads highly susceptible to rockfall hazards. Rockfalls often occur on steep slopes that experience heavy rainfall, groundwater seepage, or strong shaking from earthquakes. The unpredictable nature of these events often creates substantial problems for communities, transportation infrastructure, and the...

Multi-hazard Damage and Loss Assessment of Bridge Networks

Creator:: Burns, Patrick O.
Abstract:: The overarching objective of this study is to examine and compare the vulnerabilities of bridges combining effects of earthquake-induced ground shaking, ground failure (e.g., landslides and lateral spreading), and tsunami inundation. A parametric study is performed to understand the sensitivity of economic loss and traffic capacity with respect to the...

Finding a Place for Wood in Non-Residential Design: LEED vs. Green Globes Certification

Creator:: Henderson, Jordan M.
Abstract:: For centuries wood has served as a primary structural building material in small dwelling, large communal structures, bridges, and temporary structures. Even today wood is the dominant material in residential construction. Despite this long standing use of wood, non-residential multi-story construction in light of the green building revolution has yet...

Quantifying the Safety and Mobility Benefits of Connected Vehicle Technologies under Varying Levels of Market Penetration and Traffic Volume : An Agent-Based Modeling Framework

Creator:: Abdulsattar, Harith M.
Abstract:: The advancement of the cutting-edge technologies of advanced driver assistance systems (ADAS) hold promises to reshape the future of the transportation system. The concept of connected (CV) and connected automated vehicles (CAV) technologies are live examples of the future transportation. Vehicle communication technology is expected to impact conventional traffic conditions....

Uranium and technetium bio-immobilization in intermediate-scale permeable reactive scale barriers

Creator:: Sapp, Mandy M.
Abstract:: Groundwater at Oak Ridge National Laboratory's Field Research Center (FRC) is contaminated with U(VI) and Tc(VII), has pH values as low as 3.3, and nitrate concentrations as high as 120 mM. The objective of this research was to determine if in-situ bio-immobilization is a viable treatment alternative for this water....
