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...

Behavior of a 1/6th scale, two-story, wood framed residential structure under surge wave loading

Creator:: Wilson, Jebediah
Abstract:: The goal of this study was to develop an understanding of the nature of surge wave loading on wood framed residential structures for a variety of building configurations and test conditions. The objectives of the study were: (1) to measure forces on a 1/6th scale wood framed residential structure, (2)...

Influence of Uncertainties in Terrestrial Laser Scanning on Structural Reliability and Bridge Load Rating

Creator:: Loving, Carly K.
Abstract:: To ensure the safety of the nation’s bridges, the National Bridge Inspection Standards (NBIS) require all bridges to undergo routine load rating analyses to assess their structural capacity. Accurate geometric information for each structure is necessary for load rating analyses. This information is typically ascertained from as-built plans. Still, when...

Limit Equilibrium-Based Assessment of the Internal Stability of Geosynthetic Reinforced Soil Structures Subject to Seismicity

Creator:: Loving, Carly K.
Abstract:: Design of Geosynthetic-Reinforced Soil Structures (GRSS) require sufficient rear pullout anchoring capacity in order to maintain internal stability. Length requirements are amplified when reinforcement coverage ratios or seismicity is considered, potentially resulting in uneconomical GRSS design lengths. This study describes the influence of reinforcement length, coverage ratio, and pseudostatic seismic...

Centrifuge Modeling of Soil Response to Tsunami-like Rapid Flooding and the Subsequent Drawdown

Creator:: Exton, Margaret C.
Abstract:: Soil instability from tsunami hazards causes substantial damage to coastal infrastructure (e.g., the damage caused by the 2011 Great East Japan Tsunami, or the Heisei Tsunami). Tsunamis are unpredictable, so it is difficult to obtain field-scale measurements. Simulating tsunamis in a laboratory setting is therefore important to further understanding of...

Prediction of low temperature cracking of asphalt concrete mixtures with thermal stress restrained specimen test results

Creator:: Kanerva, Hannele K.
Abstract:: Low temperature cracking is attributed to tensile stresses induced in an asphalt concrete pavement that develop when the pavement is subjected to a cold temperature. Cracking results in poor ride quality and a reduction in service life of the pavement. Low temperature cracking has been predicted by regression equations, mechanistic...

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...

A Full-Scale Experimental Investigation of the Bearing Performance of Aggregate Pier-Supported Shallow Foundations

Creator:: Martin, John P.
Abstract:: Aggregate piers have been used for centuries, with increasing occurrence in the last few decades. Their usage has been driven by land development demand and enabled through equipment and engineering improvements. Understanding the principles controlling bearing capacities and serviceability performance has been an ongoing area of interest for structures supported...

Stability of gravel at artificially created spawning beds in uncontrolled streams

Creator:: Helland-Hansen, Erik Andreas
Abstract:: Twenty-five gabion-type structures across the main stem and tributaries of the Siuslaw River in the Oregon Coastal Range, installed to expand the available spawning area for fish, were investigated for their ability to perform gravel control functions such as trapping bedload carried by the stream or holding gravel placed behind...

Stability of heterogeneous and anisotropic slopes determined by the compound logarithmic spiral limit equilibrium method

Creator:: Stockton, Ezra J.
Abstract:: The logarithmic-spiral (log-spiral) limit equilibrium procedure for slope stability analysis rigorously satisfies both force and moment equilibrium with a failure surface geometry formulated as a function of the soil’s angle of internal friction. Within the framework of limit equilibrium, this procedure has, in the past, been primarily limited to homogeneous...
