Stability Sensitivity Of Low-Rise Steel-Moment Framed Buildings To Hazard-Independent Damage, Trey Reynolds Powell
Stability Sensitivity Of Low-Rise Steel-Moment Framed Buildings To Hazard-Independent Damage, Trey Reynolds Powell
Electronic Theses and Dissertations
Structural stability has been the subject of much research in recent years. Simply, structural stability may be vieas the ability of the structure’s response to be relatively unaffected by perturbations to its system. Stability of low-rise steel-moment framed buildings and their sensitivity to perturbations from significant damage are the focus of this work. Perturbations, or changes from the normal state of the structural system, have the ability to affect the structural response. Second-order geometric effects imposed through column axial loads, and/or initial out-of-plumbness during the construction process, are a comperturbation in steel framing systems. If the structural members subjected to …
Cargo Shipping Demand Modeling, Infrastructure Mapping, And Emission Impacts Of Selected U.S. Ports, Robert Coffman Richardson
Cargo Shipping Demand Modeling, Infrastructure Mapping, And Emission Impacts Of Selected U.S. Ports, Robert Coffman Richardson
Electronic Theses and Dissertations
This research included shipping demand modeling, infrastructure asset mapping, and impacts of carbon dioxide (co2) emission. The current volume of imports and exports was reviefor U.S. ports in the east coast, gulf coast, and west coast regions. The import and export of goods is a major part of the U.S. economy, and the volume of cargo handled by U.S. ports is expected to increase in the future as population increases. The major motivation for this thesis was the need for U.S. ports to make plans now to accommodate this expected growth in volume. Ports distribute commodities throughout the U.S., and …
An Experimental Investigation Of A Reinforced Steel Frame Via Structural Dynamics, Ethan Baker
An Experimental Investigation Of A Reinforced Steel Frame Via Structural Dynamics, Ethan Baker
Honors Theses
With the current decaying condition of America's infrastructure, a need for a more efficient inspection method is evident. The combination of Structural Health Monitoring data and data analysis tools could be a solution. In this study, laboratory data was captured for both a baseline bare-frame and a wooden wall reinforced steel structure. A MATLAB®-based computer program, the in-house SHE™ accomplishes an array of tasks, including signal processing and modal decomposition among others. A SAP2000® model contextualized the experimental data by producing trend behaviors, such as mode order or common mode shapes. Both sequential and cumulative reinforcement detection was performed on …
Evaluation Of The Use Of High Frequency Acoustic Cavitation To Improve Water Quality In Commercial Catfish Operations, Bennett Elizabeth Barr
Evaluation Of The Use Of High Frequency Acoustic Cavitation To Improve Water Quality In Commercial Catfish Operations, Bennett Elizabeth Barr
Honors Theses
Catfish processing plants must chill the water used for their fillet wash and flush and refill their piping systems frequently, requiring a pause in operations until the piping flush is complete. There is a need for a (preferably non-chemical) solution that enables the plants to chill the water less and flush their systems less often to mitigate high energy and water consumption. High amplitude acoustic waves (sonication) were introduced into water samples from catfish ponds to determine if they could be used as a replacement for chemical treatments to improve the water quality in the plant piping systems. Preliminary tests …
Flood Disaster Resilient Bridge Structures For Sustainable Bridge Management Systems, Alper Durmus
Flood Disaster Resilient Bridge Structures For Sustainable Bridge Management Systems, Alper Durmus
Electronic Theses and Dissertations
Extreme weather events are occurring at an increasing ferocity and frequency. Floods are the most comand damaging natural disaster. More than 4,400 occurrences of flood disasters have been reported globally between 1900 and 2016. As a result, around seven million people were killed and millions more were displaced. Climate impacts are expected to intensify weather related flooding events, and sea level rise expected worldwide will increase the risk of coastal disasters. Transportation infrastructure, vital to the economy and society of every country, is especially prone to the inland and coastal floods. Bridge structures are under the constant threat of these …
Validation Of Integrated Coast-Ocean Model Cche2d-Coast And Development Of Wind Model, Afshin Gazerzadeh
Validation Of Integrated Coast-Ocean Model Cche2d-Coast And Development Of Wind Model, Afshin Gazerzadeh
Electronic Theses and Dissertations
The eastern and southern coastlines of the United States are two of the most cyclone-prone areas of the world. The effects of tropical cyclones vary mainly depending on wind intensity and geological features of the coast that it is crossing. Higher winds potentially generate higher storm surges and consequently larger floods occur along the coastlines. Therefore, it is critical to accurately predict winds, storm surge, and waves associated with a hurricane. In the present study, an integrated coastal and ocean process model, CCHE2D-Coast, is validated by assessing the model’s capabilities in simulating coast-ocean circulations driven by the astronomical tides on …
