High performance friction-type bearings for seismic isolation
Seismic isolation is effective in protecting both structural and non-structural elements during earthquakes. One of the most commonly used base-isolation systems is the friction pendulum system (FPS). It provides excellent ... -
How The Weather, Land Use, and Infrastructure Influence Non-Motorized Mode Choices
Compared to many other developed nations, the United States is largely reliant on automobiles for satisfying the daily transportation needs of its citizens. This large demand of auto trips produces excessive amounts of ... -
Human-Centered Simulation Modeling to Facilitate Critical Infrastructure Resilience Planning
Planning for timely, effective, and efficient post-disaster infrastructure restoration is critical to prevent prolonged disruptions. Infrastructure resilience planning aims to anticipate damages and disruptions in service, ... -
Hydrodynamics and Sediment Transport at the River-Ocean Interface: Analytical and Laboratory Investigations
This study presents a combination of numerical and analytical investigations of fluid and sediment transport mechanics through the river-ocean interface. This region is defined broadly as the region within the river that ... -
Hydrodynamics and sediment transport in the Duwamish River Estuary
Nearly two-thirds of the world’s major cities have been built around estuaries. As populations have grown, many estuaries have been modified, impacting their hydrodynamic regime. Urbanized estuaries, which are typically ... -
Hydrologic sensitivities of western U.S. rivers to climate change
(2013-11-14)As the climate continues to change, increasing temperatures and changes in precipitation will lead to fundamental changes in the seasonal distribution of streamflow, especially in the western United States where snowmelt ... -
Hygrothermal Performance of Energy Retrofits in Buildings: An Assessment of the Residential Building Stock in the U.S.
Improving buildings’ energy efficiency has been widely recognized as one of the most versatile and effective means of reducing energy consumption in existing buildings. However, recent investigations of retrofits in ... -
Identification and Fate of Bioactive Transformation Products of Pharmaceuticals and Industrial Antioxidants
Human society discharges complex chemical mixtures into the aquatic environment that cause various adverse effects to aquatic organisms and humans. Upon discharge, organic chemicals typically form multiple transformation ... -
Identification of Urban Scaling Behavior for Transportation Mode Share
Urban scaling effects provide a means to formulate a general understanding of the processes that govern transportation system outcomes. Urban scaling analysis assumes that the quantity of interest follows a power-law ... -
Impact of Beam Strength on Seismic Performance of Chevron Concentrically Braced Frames
Special concentrically braced frames (SCBFs) are a popular choice for lateral force resisting systems in regions of high seismicity. SCBFs with braces oriented in a chevron (or inverted V) configuration are often preferred ... -
Impact of Connection Type on Performance of Non-Seismic Concentrically Braced Frames
Concentrically braced frame (CBF) structural systems resist lateral loads using braces framed diagonally between frame work points defined at the intersection of beam, column, and brace centerlines. In the past few ... -
Impact of Homeless Encampments on State Department of Transportation Right of Way
Homelessness is a severe problem in the United States. Homelessness is severely stigmatized in our society as it is driven largely by systemic and racist attitudes in our country. This is also a considerable issue for ... -
Impact of Retarder-Induced Roughness on Shear Friction Capacity using Conventional and High-Strength Reinforcement
Shear friction is used to transfer shear forces between two reinforced concrete members or two members with dissimilar materials. Shear transfer across a plane represents a complex phenomenon that depends on the interactions ... -
Impacts of an M9 Cascadia Subduction Zone Earthquake on Structures Located in Deep Sedimentary Basins
Thirty scenarios of magnitude-9 Cascadia subduction interface earthquakes were simulated by a research team from the United States Geological Survey and the University of Washington. These motions were strongly modified ... -
Impacts of Cascadia Subduction Zone M9 Earthquakes on Bridges in Washington State: SDOF Idealized Bridges
The Cascadia Subduction Zone has the potential to generate Magnitude 9 earthquakes that couldhave large impacts on bridges throughout western Washington State. The likelihoods of damage to bridges during an M9 event at ... -
Impacts of Cascadia Subduction Zone M9 Earthquakes on Bridges in Washington State
The Cascadia Subduction Zone (CSZ) poses a major seismic hazard to the western portions of Washington State, Oregon State, and Northern California. To plan for community resilience, it is important to understand the impacts ... -
Impacts of future climate and landuse on water resources in Espírito Santo, Brazil
Increasing temperature and precipitation changes are expected to bring fundamental changes to the country of Brazil as predicted by Global Climate Models (GCMs) (IPCC, 2007). Potential effects of climate change in Brazil ... -
IMPACTS OF LATERAL SPREADING AND UPSTREAM CONDITIONS ON BUOYANT RIVER PLUMES: MIXING, STRUCTURE AND PLUME DYNAMICS
(2013-04-17)This dissertation investigates the nature of physical processes associated with buoyant river plumes under the impacts of rotation, lateral spreading and upstream conditions. Two sets of laboratory experiments, one focused ... -
Implementation, Verification, Validation, and Application of Two Constitutive Models for Earthquake Engineering Applications
Human and economic losses caused by earthquake-induced soil liquefaction underscore the importance of assessing liquefaction hazards, both by determining whether a soil is likely to liquefy and by estimating consequences ... -
Implications of Glacier Recession for Water Resources
Numerical simulation models of hydrologic processes can be effective tools for inferring the consequences of environmental change for water resource systems. In river basins that originate in partially glacierized catchments ...
