Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

Creator:: Lathrop Eve D.
Abstract:: The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...

Assessment of Multi-year Hydrologic Performance of Bioretention Facility using Real-Time Sensors

Creator:: Alyousef, Hashim A.
Abstract:: Bioretention facilities are emerging as a popular way to deal with stormwater runoff in urban environments and address its concerns. Real-time sensors installed in bioretention facilities aid in understanding the performance and feasibility of such facilities over time. A bioretention facility in Corvallis, Oregon was monitored for a study period...

Developing tools to improve tsunami resilient design of coastal structures

Creator:: Thomas, Seth Alan
Abstract:: Over the last decade the world has seen three major tsunamis strike the coasts of Indonesia, Samoa, and Chile. These tsunamis have caused significant losses of life and property on the coastal cities of these and nearby countries. The NEES (Network for Earthquake Engineering Simulation) Housesmash project was created to...

Use of Controlled Blasting to Quantify the Dynamic, In-Situ, Nonlinear Inelastic Response of Soils

Creator:: Jana, Amalesh
Abstract:: The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...

Predicting pore pressure response in in-situ liquefaction studies using controlled blasting

Creator:: Eller, James Michael
Abstract:: Originally used as a method to densify loose soils, controlled blasting has expanded its applicability to geotechnical engineering by becoming a research tool to physically generate liquefaction for full-scale in-situ tests, ranging from seismic performance of deep foundations to evaluating ground improvement techniques. Current methods used to design the blasting...

Evaluation and Modification of a Thixotropic Fluid Model for Liquefaction Triggering with Application to Laboratory Tests and Lateral Spreading

Creator:: Brown, Tovey M.
Abstract:: Earthquake-induced liquefaction is a large contributor to damage observed following seismic events. Commonly observed damage consists of significant ground and structural failure due to the deformation of large volumes of soil due to soil liquefaction and lateral spreading. A significant focus of geotechnical seismic research concentrates on the development and...

Region-Specific Investigation of the Cone Penetration Test for Preliminary Classification and Estimation of Preconsolidation Stress, Undrained Shear Strength, and Cyclic Resistance of Transitional Silts

Creator:: Ortiz, Susan Christine
Abstract:: The Cone Penetration Test (CPT) has been widely-adopted for rapid, cost-effective exploration of the subsurface and reduction in the effort associated with drilling, sampling, and laboratory testing of soil. The adoption of the CPT has stemmed in part to the correlation of measurements to preliminary soil classification, stress history, drained...

Ground Improvement and Liquefaction Mitigation using Driven Timber Piles

Creator:: Gianella, Tygh N.
Abstract:: Seismically-induced liquefaction represents a major cause of damage to civil infrastructure and can result in significant damage following major earthquakes. Liquefaction can occur when earthquake ground motions raise pore-water pressures in loose, sandy soil, resulting in a substantial decrease of soil strength. Owing to the potential for instability following liquefaction,...

An investigation into the role of spatial variability on liquefaction consequence severity

Creator:: Cary, John R.
Abstract:: During the Canterbury Earthquake Sequence (CES) in Christchurch, NZ, an estimated $15B in damages occurred due to liquefaction-induced phenomena, illustrating the importance of understanding site-specific responses to seismic ground motions, as well the importance of accurately predicting liquefaction severity. One potential method for improving the understanding of how a site...
