Beach Dune Subsurface Hydrodynamics and the Formation of Dune Scarps

Creator:: Bond, Hailey G.
Abstract:: The formation of beach scarps is a challenging morphodynamic phenomenon that the coastal community has yet to capture in coastal change models. Understanding scarp formation is crucial to accurately predicting coastal erosion and vulnerability during extreme events, as models without parameters for scarp formation and development severely underpredict total erosion...

Numerical Characterization and Modeling Uncertainty of Frame-Spine and Frame-Spine-FLC Full-Scale Specimens Tested at E-Defense Shake-Table

Creator:: Astudillo, Bryam
Abstract:: The characterization of the seismic performance of structures relies on numerical simulations. However, estimates of seismic response are subject to various sources of uncertainty, including modeling uncertainty. This research estimated the response of two full-scale structural specimens composed of a moment resisting frame, elastic spines, and force-limiting connections (FLC), which...

Radar and Optical Remote Sensing of Submesoscale Frontal Features

Creator:: Simpson, Alexandra J.
Abstract:: The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

Characterization of reinforced fill soil, soil-reinforcement interaction, and internal stability of very tall MSE walls

Creator:: Walters, James J.
Abstract:: In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...

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...

The Fundamental Behavior of CLT Floor-to-Wall Connections in Fire

Creator:: Redus, James Aaron
Abstract:: This thesis focuses on the fundamental behavior of CLT floor-to-wall connections during a fire. Cross-laminated timber (CLT) panelized structures rely on floor-to-wall connections for the load path and stability of the structure. Additionally, the fire performance of these connections is critical to prevent horizontal or vertical fire spread within these...

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...

Advancements Toward the Simulation of Steel Structures in Fire Using OpenSees

Creator:: Gordon, James A.
Abstract:: Since the collapse of World Trade Center building number seven (WTC7), significant research has been done to understand the behavior of steel structures in fire and enable engineers to account for the behavior of steel framing systems exposed to fire during design. Despite these efforts, there are still significant barriers...

Applying the Mixed Logit Model with Heterogeneity in Means and Variances to Pedestrian Injury Severity Outcomes

Creator:: Umphress, James
Abstract:: Walking is the single most universal mode of transportation in the world, but being a pedestrian exposes a traveler to high risk. Historically, pedestrians have consistently experienced disproportionately high rates of fatalities and severe injuries in traffic crashes. Research has probed into factors influencing pedestrian crash injury severity outcomes, but...

A Multivariate Comparison of Drone-Based Structure from Motion and Drone-Based Lidar for Dense Topographic Mapping Applications

Creator:: Simpson, Chase H.
Abstract:: Unmanned aircraft systems (UAS), also known as drones, are an increasingly popular method of collecting surveying and mapping data. Two common drone-based mapping techniques are lidar and structure from motion (SfM) photogrammetry, and a frequently-heard (yet nearly impossible to answer) question is: “which is better?” The most common metric for...
