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...

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...

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...

Extreme Wave Runup and Runup Variability on Beaches

Creator:: Li, Chuan
Abstract:: Wave runup is an important physical process that affects nearshore sediment transport, coastal erosion, and flooding. Large and unexpected runup events can also be dangerous to beach goers. Extreme runup statistics are essential parameters used in engineering design of marine structures and in coastal management. Although the study of runup...

Enhancing Design of Geosynthetic-Reinforced Soil Supporting Spread Footings

Creator:: Xie, Yonggui
Abstract:: Internal stability of Geosynthetic-Reinforced Soil (GRS) walls are conventionally assessed using lateral earth pressure methods. Determination of these pressures is a key component of limit state design as it enables determination of mobilized resisting forces in reinforcements needed to ensure stability and function of the GRS structure. However, conventional methods...

Ultimate and serviceability limit state reliability-based axial capacity of deep foundations

Creator:: Reddy, Seth C.
Abstract:: Deep foundations are necessary for the construction of many structures, such as bridges and buildings, located in areas unsuitable for shallow foundations. Owing to the inherent variability of soil and the complex changes that occur in the soil adjacent to deep foundations as they are installed, the ability to accurately...

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,...

Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

Creator:: Kirkham, William J.
Abstract:: There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...

Cross-Laminated Timber Shear Walls with Toe-Screwed and Slip-Friction Connections

Creator:: Fitzgerald, Dillon M.
Abstract:: Timber engineering is currently in the midst of a significant evolution due to the rise of mass timber products, like cross-laminated timber (CLT). Increasing numbers of structural engineers are facing the challenge of designing lateral-force-resisting systems (LFRS) for multistory CLT structures. LFRS solutions such as steel frames, concrete cores, or...

The seismic geotechnical modeling, performance, and analysis of pile-supported wharves

Creator:: McCullough, Nason J.
Abstract:: This dissertation presents the results of a research effort conducted to better understand the seismic performance and analysis of pile-supported wharves. Given the limited number of well-documented field case histories, the seismic performance of pile-supported wharves has been poorly quantified, and the analysis methods commonly employed in engineering practice have...
