Abstract Two precast prestressed high-strength concrete and high-strength self-consolidating concrete pedestrian bridges were designed and erected in Rolla, Missouri, for an in situ investigative study to monitor time-dependent losses. Using the temperature and strain data monitored by the vibrating wire strain gauges within the beam cross sections, time-dependent losses were determined and compared between the bridges and various empirical expressions presented by AASHTO and the Precast/Prestressed Concrete Institute. © 2013 American Society of Civil Engineers.

Faulty Measurements And Shaky Tools: An Exploration Into Hazus And The Seismic Vulnerabilities Of Portland, Or, Brittany Ann Brannon

Dissertations and Theses

Events or forces of nature with catastrophic consequences, or "natural disasters," have increased in both frequency and force due to climate change and increased urbanization in climate-sensitive areas. To create capacity to face these dangers, an entity must first quantify the threat and translate scientific knowledge on nature into comprehensible estimates of cost and loss. These estimates equip those at risk with knowledge to enact policy, formulate mitigation plans, raise awareness, and promote preparedness in light of potential destruction. Hazards-United States, or Hazus, is one such tool created by the federal government to estimate loss from a variety of threats, …

Neighborhood Commercial Corridor Change: Portland, Oregon 1990-2010, Kelly Ann Howsley-Glover

Dissertations and Theses

Commercial corridors in neighborhoods experiencing change have been relegated to a footnote in research on residential phenomena. It is taken for granted that the process of change experience by businesses within these neighborhoods mirrors that of the residential change. This assumption is often predicated on the underlying model of invasion succession, suggesting that inmovers displace native populations, whether they are residents or businesses. Analyzing time series data on neighborhood commercial corridor change, research attempted to first test data against the invasion succession model to see if it is an effective framework for analysis. Second, through comparison of case study areas …

Directional Phytoscreening: Contaminant Gradients In Trees For Plume Delineation, Matt A. Limmer, Mikhil K. Shetty, Samantha Markus, Ryan Kroeker, Beth L. Parker, Camilo Martinez, Joel Gerard Burken

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Tree Sampling Methods Have Been Used in Phytoscreening Applications to Delineate Contaminated Soil and Groundwater, Augmenting Traditional Investigative Methods that Are Time-Consuming, Resource-Intensive, Invasive, and Costly. in the Past Decade, Contaminant Concentrations in Tree Tissues Have Been Shown to Reflect the Extent and Intensity of Subsurface Contamination. This Paper Investigates a New Phytoscreening Tool: Directional Tree Coring, a Concept Originating from Field Data that Indicated Azimuthal Concentrations in Tree Trunks Reflected the Concentration Gradients in the Groundwater Around the Tree.To Experimentally Test This Hypothesis, Large Diameter Trees Were Subjected to Subsurface Contaminant Concentration Gradients in a Greenhouse Study. These Trees …

Transforming Architecture: Engaging The Built Environment, Ryan G. Hier

Architecture Masters of Science Program: Theses

Contemporary society is transfixed by the newest piece of technology. More often than not these devices serve as commodities; eliminating a certain amount of burden from daily life. The architectural realm is no different. Building design decisions are constantly scruti­nized by their ability to perform, with respect to energy consumption and conservation. However, there is a different type of building performance worth considering: the act of transformation. Transformable architecture has the abili­ty to change structure, space, and function through physical movement of the architecture.

In an age where technology suc­ceeds in disengaging humans from interaction with each other, it can …

Boomtown: A Momentary Community, Elizabeth G. Hawks

Architecture Masters of Science Program: Theses

“Gillette Syndrome” describes a condition within a city undergoing rapid growth, usually due to the introduction of a new industry within the city or more specifically, the extraction of a newly discovered natural resource. Symptoms of the syndrome are an increase in crime and decay within a city and a decrease in community identity.

Global oil prices continue to rise as the resource becomes more difficult to extract from the earth’s layers. The new price of oil necessitates the extraction of crude through methods that were previously too expensive to justify.

These new methods are utilized for extracting oil in …

Evaluating Satellite Products For Precipitation Estimation In Mountain Regions: A Case Study For Nepal, Nir Y. Krakauer, Soni M. Pradhanang, Tarendra Lakhankar, Ajay K. Jha

Publications and Research

Precipitation in mountain regions is often highly variable and poorly observed, limiting abilities to manage water resource challenges. Here, we evaluate remote sensing and ground station-based gridded precipitation products over Nepal against weather station precipitation observations on a monthly timescale. We find that the Tropical Rainfall Measuring Mission (TRMM) 3B-43 precipitation product exhibits little mean bias and reasonable skill in giving precipitation over Nepal. Compared to station observations, the TRMM precipitation product showed an overall Nash-Sutcliffe efficiency of 0.49, which is similar to the skill of the gridded station-based product Asian Precipitation-Highly Resolved Observational Data Integration Towards Evaluation of Water …

Dynamic Properties Of Fine-Grained Soils Engineered With A Controlled Organic Phase, B. Bate, H. Choo, S. E. Burns

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Soils with high organic content are frequently encountered beneath earthquake sensitive infrastructure, such as bridges or levees. Historically, the dynamic properties of these organically rich soils have been difficult to predict due to the heterogeneity of the natural organic matter that is found in natural soils, even though their response to dynamic loading remains critical to assessing the ongoing stability of the infrastructure. In this study, an experimental investigation was performed on a montmorillonite soil that was modified with a controlled organic phase. Quaternary ammonium cations were exchanged onto the soil particle surfaces through cation exchange with the clay's naturally …

Phasing-Out Fossil Fuel Subsidies In Venezuela: A Transportation Planning Perspective, Mariana E. Marmol

LSU New Orleans Theses and Dissertations

This research examines the feasibility of a gasoline and diesel consumer subsidy phase-out in Venezuela from a transportation planning perspective. It surveys the literature and discusses case studies from Iran, Brazil, and Bolivia in order to identify the lessons that Venezuela can learn from these countries’ successes and mistakes. It examines how strengthening and investing in the public transportation system can be used as a means to gain public support for the reform. I discuss the current political, social, and economic conditions that make a fossil-fuel subsidy reform difficult, and offer suggestions from a transportation planner’s perspective on how the …

Analysis Of Urban Water Use And Urban Consumptive Water Use In Nebraska, Case Study In The City Of Lincoln, Grand Island And Sidney, Yao Li

Community and Regional Planning Program: Theses

The trends of increasing water demand and drought occurrences in Nebraska’s urban areas pose a new crucial issue to water resource management. Former studies in Nebraska mainly focused on rural water demand caused by intensive agricultural irrigation, while largely ignoring the growing municipal water use. Therefore, this thesis aims to investigate total water use and consumptive water use in three major urban land use categories of residential, CIO (commercial, industrial and others), and open space. Three case cities are City of Lincoln, Grand Island and Sidney. First, a reliable and feasible methodology of estimating consumptive water use is developed based …

How Kaizen Group Leader Selection Affects Group Participation, M. Joleen Byerline

Masters Theses & Specialist Projects

Organizational communication research indicates group member participation increases as the legitimate power differences among group members decreases. Lean principles and practices indicate Kaizen Event members will contribute regardless of legitimate power levels, due to member training, education, and the Lean team-oriented culture. Further study is needed to determine if Lean culture and training maximize group member contribution, or if legitimate power levels in Lean environments manipulate participation. The focus of this case study is a central Kentucky Lean manufacturing organization that practiced Lean principles for at least three years and completed a Kaizen Event within twelve months previous to the …
