Bridge Damage State Detection Based on Strain-Based Wireless Structural Health Monitoring

Creator:: Slaven, Kelli R.
Abstract:: The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...

Assessing the Risk and Resilience of Coastal Communities: An Application to the Joint Seismic-Tsunami Hazard at Seaside, Oregon

Creator:: Sanderson, Dylan, R.
Abstract:: This thesis presents two conceptually linked papers outlining methodologies to improve community resilience. Both papers employ Seaside, Oregon as a testbed community and consider the seismic-tsunami hazard posed by the Cascadia Subduction Zone. The first paper presents a framework to deaggregate the results of a multi-hazard, multi-infrastructure, damage analysis by...

Physical Modeling of Progressive Damage and Failure of Wood-Frame Coastal Residential Structures Due to Waves and Surge Forces

Creator:: Duncan, Sean M.
Abstract:: A physical model study was performed to examine the forces and response of 1:6 scale wood-frame coastal residential structures subjected to storm surge and waves. An on-grade and an elevated specimen were tested and exposed to regular waves with varying water depths and wave heights to simulate Hurricane Sandy’s conditions....

Numerical assessment of steel plate shear wall with coupling (SPSW-WC) system design procedure

Creator:: Li, Wennan
Abstract:: The Steel Plate Shear Wall (SPSW) system, is an innovative seismic lateral force resistant system, which has experienced increased use over the last three decades. The SPSW system is composed of boundary elements which anchor web plates that develop diagonal tension fields. A number of SPSW buildings have been built...

Height Modernization from Static GPS Networks in Oregon: Evaluating NGS Guidelines and OPUS-Projects

Creator:: Kerr, Darren J.
Abstract:: Determining accurate elevations is important for many engineering and scientific applications, and finding these heights via GNSS increases efficiency and significantly reduces the costs as compared to precise geodetic leveling. The National Geodetic Survey (NGS) has published guidelines for determining both ellipsoidal and orthometric heights with GPS to within 2...

Experimental and numerical modeling of wave height attenuation by emergent coastal vegetation

Creator:: Blackmar, Philip James
Abstract:: Coastal vegetation dampens waves which can provide benefits to the local area, but existing literature shows large variations in the degree of wave height attenuation depending on plant properties and wave conditions. Better knowledge of how to predict the wave height decay accurately in different types of vegetation may help...

Evaluation of the Performance of Lateral Spread Displacement Empirical Models for Subduction Zone Earthquake Case Histories

Creator:: Bunn, Michael
Abstract:: Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...

Small Unmanned Aircraft Systems (UAS) for Engineering Inspections and Geospatial Mapping

Creator:: Javadnejad, Farid
Abstract:: Small unmanned aircraft systems (UAS) carrying consumer-grade nonmetric cameras are increasingly utilized to generate high-resolution 3D geospatial data. Low cost, ease of operation, widespread availability and low altitude maneuvering capabilities of UAS, as well as the rapid development of technology and methods, make UAS-based photogrammetry applicable to many civil engineering...

Observations and prediction of intermittent sediment suspension in the surf zone

Creator:: Yoon, Hyun Doug
Abstract:: In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...

Performance-Based Design Methodology for Using Emergent Vegetation to Mitigate Wave Overtopping

Creator:: Ostrow, Kayla
Abstract:: To facilitate the design of Natural and Nature-Based Features (NNBF) for flood protection, this thesis expands an existing engineering design methodology to NNBF systems. The existing approach is a Level III reliability method for the performance-based design of traditional coastal engineering systems. The expanded methodology incorporates uncertainties inherent to both...
