Determining Earthquake Impacts On Arkansas' Roadway Network: An Application Of Hazus., Simon Rothwell
Determining Earthquake Impacts On Arkansas' Roadway Network: An Application Of Hazus., Simon Rothwell
Civil Engineering Undergraduate Honors Theses
Natural hazards are a dangerous and unpredictable aspect of life on earth. They can cause devastating damage to our surroundings that makes movement of people, goods, and emergency services difficult. There is a need to plan for these disasters to ensure that damages to our infrastructure and people are minimized. It can be difficult for planners to determine which parts of a roadway network are most vulnerable to a specific disaster and what their impact on the rest of the network may be. This thesis uses a nationally available natural disaster estimation tool developed by FEMA called “Hazus” (FEMA, 2020). …
Design Of A Freight Transportation Outreach Curriculum, Breanna Stoesz
Design Of A Freight Transportation Outreach Curriculum, Breanna Stoesz
Civil Engineering Undergraduate Honors Theses
This project is centered around finding a solution to the shortage of truck drivers within the freight industry. Specifically, this project aims to lessen this shortage by ensuring potential future drivers are aware of the benefits of the industry and are encouraged to consider this career path for themselves. By producing an engaging and educational freight transportation curriculum for middle and high school students to go through in outreach programs, these students would have an increased likelihood of joining the trucking profession and encourage others to become informed about the profession as well. In addition to the direct driving role, …
Community Transportation Needs And Willingness To Use Shared Micromobility: A Case Study Of Fort Smith, Arkansas, Anthony Michael Kammerer
Community Transportation Needs And Willingness To Use Shared Micromobility: A Case Study Of Fort Smith, Arkansas, Anthony Michael Kammerer
Civil Engineering Undergraduate Honors Theses
Shared micromobility is utilized in “targeted service areas with the usage generally intended for short trips such as "first- and last-mile" connections to complete trips made via other modes, including transit” (Price et al., 2021). In the United States, this practice has especially taken off with the implementation of sharing-based systems. This is evidenced by ridership numbers in the United States growing from 84 million riders nationwide in 2018 to 136 million riders in 2019 (NACTO, 2020). Users often use their smart phone or another similar device to unlock the vehicle after paying a fee on the device through their …
Countermeasures For Pedestrian-Involved Accidents On Interstate-Highways, Anna C. Hunter
Countermeasures For Pedestrian-Involved Accidents On Interstate-Highways, Anna C. Hunter
Civil Engineering Undergraduate Honors Theses
Pedestrian access to the Interstate is prohibited, but many pedestrian-involved accidents still occur on the Interstate in the United States. This project is a case study of West Memphis, Arkansas, which has the second highest occurrence of pedestrian-involved accidents on the Interstate in Arkansas. The study site location includes a segment of Interstate I-40 which is at- grade. The surrounding area contains several different land-uses, which is believed to be the primary generator of these accidents. The goal of this project is to determine the primary causes of these accidents and determine potential countermeasures to reduce the crash rate for …
Turbulent Effects On Building Pressure Using A Two-Dimensional Finite Element Program, Jonese Woods
Turbulent Effects On Building Pressure Using A Two-Dimensional Finite Element Program, Jonese Woods
Civil Engineering Undergraduate Honors Theses
Much of the knowledge about building aerodynamics today was obtained from physical testing like wind tunnel testing. Physical testing is time-consuming and very expensive. As a result, computational methods like the finite element method are being explored for use in building aerodynamics. Despite several years of research, there is still not a clear understanding of the peak pressure on buildings due to turbulence. Many of the research thus far has focused on comparing different computational methods. However, much work is needed in understanding the capability of the individual methods. In this work, a two-dimensional finite element program is used to …
Tension Splitting Strength Of Bcsa Concrete Cylinders, Andrew Steven Deschenes
Tension Splitting Strength Of Bcsa Concrete Cylinders, Andrew Steven Deschenes
Civil Engineering Undergraduate Honors Theses
The focus of this research was to compare the tension splitting strength (TSS) of belitic calcium sufloaluminate (BCSA) cement concrete to tensile strength predicted by the American Concrete Institute (ACI) and to similarly proportioned portland cement (PC) concrete. BCSA is a rapid-setting cement with higher early strength, higher ettringite content, and lower calcium silicate hydrate (C-S-H) content than PC. PC and BCSA cement concrete cylinders were broken at different ages in both uniaxial compression and TSS. It was found that BCSA had a similar TSS to both the ACI prediction and PC TSS, but the results require further testing for …
Controlling Relative Humidity Using Glycerin, Juan Martinez
Controlling Relative Humidity Using Glycerin, Juan Martinez
Civil Engineering Undergraduate Honors Theses
A series of tests were conducted to control relative humidity (RH) using a bubbler system that contained a series of glass jars and glass vials filled with different concentrations of glycerin. The relative humidity within the glass jars was measured. The total time interval for each laboratory test was 48 hours. During the first 24 hours a pump was used to bubble air through the glycerin solution. During the second 24 hours, the pump was turned off, and the RH within the system was monitored within the closed system. Target RH measurements from 100% to a 0% were obtained. The …
Service Learning Through Extracurricular Activities: Development And Implementation Of A Transportation Engineering Learning Module, Karla Diaz Corro
Service Learning Through Extracurricular Activities: Development And Implementation Of A Transportation Engineering Learning Module, Karla Diaz Corro
Civil Engineering Undergraduate Honors Theses
This project developed an easy to implement, low-cost learning module. The module has students compare and contrast the challenges of gathering comprehensive and quality transportation data through advanced technologies and traditional approaches while introducing traffic engineering topics like traffic signal timing. The modules target middle through high school students and first and second year undergraduate engineering students. The learning modules introduce transportation engineering using an engaging open-source computer simulation game adapted by students at the University of Arkansas, as part of a capstone project. The activities in the learning modules require off-the shelf, low-cost computer hardware, making it easy for …
Young’S Modulus As A Measurement To Estimate Damage Related With Alkali-Silica Reaction In Concrete., Anazaria J. Ortega Gonzalez
Young’S Modulus As A Measurement To Estimate Damage Related With Alkali-Silica Reaction In Concrete., Anazaria J. Ortega Gonzalez
Civil Engineering Undergraduate Honors Theses
The main purpose of this research is to compare two nondestructive methods to assess Alkali-Silica reaction (ASR) in concrete. Fifteen concrete prisms were cast using aggregates with different Alkali-Silica reactivity such as Jobe sand and Van Buren sand. The change in strain, shear wave velocity and Young’s modulus were determined according to ASTM C129 and ASTM C215, respectively. This data was collected by Dillon K Self, who determined that the shear wave velocity and strain are inversely proportional. However, when single cracking in the concrete specimen transition to map cracking, the shear wave velocity dropped significantly, whereas the strain value …
