Investigating The Effects Of Aggregate Size And Reinforcement On Asr Cracking In Concrete Structures Studied With Different Evaluation Methods, David Joseph Bianco

Theses and Dissertations

The objective of this thesis is to investigate different (non-destructive) evaluation methods to assess the effects of reactive aggregate size and reinforcement on ASR affected concrete. It has been shown in previous literature that reactive coarse aggregates lead to more expansion as opposed to reactive fine aggregates. However, there is a lack in the literature exhibiting this relationship using different evaluation methods, such as acoustic emission (AE) and ultrasonic pulse velocity (UPV). Also, the literature does not emphasize the role this relationship plays when the concrete is imposed with stress boundary conditions. Non-destructive test methods, including acoustic emission, are becoming …

Structural Design Of Pool House In The City Of Columbia, Nathan F. Gates

Senior Theses

This report presents a structural design for a one-story pool house in the City of Columbia. The most important part of the project was determining critical horizontal and vertical loads, and designing each member in accordance to those governing loads. The loads we analyzed were dynamic, dead, live and seismic. By means of the LRFD method, the greatest possible load combination was calculated, combining the previously mentioned loads. These load combinations were different for each analysis, as the loading pressures will change depending on what structural system is being analyzed. This comprises the large part of the report and of …

Robust Maximum Flow Network Interdiction Problem, Darshan Rajesh Chauhan

Dissertations and Theses

In this thesis, a maximum flow-based network interdiction problem considering uncertainties in arc capacities and interdiction resource consumption is solved. The problem consists of two entities with opposing objectives: the goal of the adversary is to maximize the flow of illicit drugs through the network, while the goal of the interdictor is to minimize the maximum flow by completely interdicting arcs given a specified amount of resources. Lack of complete information about the usage patterns of the transportation network by the adversary results in an uncertain estimate of arc capacity and resources required for interdiction by the interdictor. To account …

Mohammed Aljuboori

The University of Wisconsin – Milwaukee, 2019

Under the Supervision of Dr. Habib Tabatabai

Precast concrete systems are widely used in a variety of structures such as parking garages, residential units, shopping centers, and transportation stations. In some cases, precast structures are preferred over conventional cast-in-place (CIP) concrete conventional structures because of ease of construction, rapid implementation, and lower levels of energy consumption. One area where precast systems have traditionally been at a disadvantage is high seismic applications. In seismic regions, precast concrete structures must have …

The Influence Of Citric Acid On Setting Time And Temperature Behavior Of Calcium Sulfoaluminate-Belite Cement, Edgar Soriano

Civil Engineering Undergraduate Honors Theses

Today the need to opt for alternative cementitious materials is growing due to environmental reasons and construction time frames that portland cement cannot always satisfy. Calcium Sulfoaluminate (CSA) cements are a strong candidate to supplement or replace portland cement in the construction field for certain applications. In the United States, CSA cement has been limited mostly to pavement repairs because of its rapid initial setting time. The chemical compound responsible for this phenomenon is the alumina. This compound and sulfate are present in larger proportions compared to portland cement. The purpose of this research is to study how the use …

Optimizing The Performance Of Complex Engineering Systems Aided By Artificial Neural Networks, Khalil Qatu

Electronic Theses and Dissertations

In the first problem Polyetherimide graphene nanoplatelets papers (PEIGNP) were tested with different graphene loadings varying from 0-97 weight percent (WT%). The resulting stress-strain curves were utilized to develop two ANN models. Stress-controlled and strain-controlled models. Both models shoan excellent correlation to the experimental. Several Mechanical properties were calculated from the predicted stress-strain curves namely; toughness maximum strength maximum strain and maximum tangent modulus. Both models captured the same overall behavior of the PEIGNP composite. However the strain-controlled model was found to predict lower stress than the stress-controlled model. Finally a Graphical User Interface (GUI) was developed to aid in …

Stabilization Of Dredged Materials In Ohio: An Investigation Of Mechanical, Chemical And Biological Dewatering Techniques, Erika Howard

Williams Honors College, Honors Research Projects

Each year, materials are excavated from oceans and lakes in order to keep the waterways open so that ships can safely pass through. These excavated, or dredged, materials are then discarded, usually being returned to the body of water from which they were removed. Beginning in 2020, the Ohio Environmental Protection Agency (OEPA) will no longer allow this to occur. Therefore, the purpose of this project is to investigate beneficial uses for dredged materials in Lake Erie, and to address the best management practices for dewatering these materials, as set forth in the Lake Erie Protection and Restoration Plan created …

The Passive Effects Of Full-Gateway, In-Street Signs On Vehicular Speed, De'lon Dixon

Skill Retention For Driving Simulation Experiments, Nikhil Ravindra Sarwate

ETD Archive

Whether driving a car in the real world or a simulator vehicle in a computer generated world, the procedural aspects of driving are very similar. The steering wheel is used to control the direction of the vehicle while the accelerator and brake pedals are used to control the speed. This similarity means that people who already possess the skill of driving in the real world are expected to transfer those existing skills to drive a simulator vehicle. Recognizing the need for skill transference, the typical protocol for conducting driving simulation experiments includes a practice drive, which affords participants the opportunity …

A New Multidimensional Psycho-Physical Framework For Modeling Car-Following In A Freeway Work Zone, Taylor Lochrane

Electronic Theses and Dissertations

As the United States continues to build and repair the ageing highway infrastructure, the bearing of freeway work zones will continue to impact the capacity. To predict the capacity of a freeway work zone, there are several tools available for engineers to evaluate these work zones but only microsimulation has the ability to simulate the driver behavior. One of the limitations of current car-following models is that they only account for one overall behavioral condition. This dissertation hypothesizes that drivers change their driving behavior as they drive through a freeway work zone compared to normal freeway conditions which has the …
