Evaluation And Development Of Cpt Based Pile Design In Nebraska Soils, Alex Silvey

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Cone penetration testing (CPT) is a well established geotechnical subsurface investigation technique commonly used for site characterization and soil classification. The CPT gives real time end resistance, side friction, and pore pressure readings. Axially loaded piles also share these two resistance mechanisms, suggesting the cone can be considered similar to a miniature pile. This study focused on evaluating eight CPT methods prediction of pile bearing capacity. The Nebraska Department of Roads (NDOR) conducts dynamic load tests (PDA) of driven pile to verify pile capacity for bridge foundations. 91 comparisons of CPT logs and PDA data were evaluated. CPT prediction methods …

On Thermal Bowing Of Concrete Sandwich Wall Panels With Flexible Shear Connectors, Fray Pozo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thermal bowing, often referred as bulging or out-of-plane wall deflection, is a common issue on sandwich panel walls caused by a temperature differential between a building interior temperature and the environment. The stresses caused by temperature changes in concrete members are widely known in the practice of bridge design, but not on sandwich wall panels. For sandwich wall panel applications, it is common to have non-composite panels when the designer expects a high temperature gradient, what yields a less economical design, but reduces the bowing.

This project aimed to validate current assumptions regarding the heat flow in sandwich wall panels …

Decision-Making Framework For The Selection Of Sustainable Alternatives For Energy-Retrofits, Amirhosein Jafari

Civil Engineering ETDs

Buildings are major consumers of energy worldwide. On the other hand, over 60% of the US housing inventory is over 30 years old and a large number of these homes are energy inefficient. Therefore, it is essential to target the existing building stock for energy efficient interventions as a key to substantially reduce the adverse impacts of buildings on the environment and economy.

Building energy retrofitting has emerged as a primary strategy for reducing energy use and carbon emissions in existing buildings. An energy retrofit can be defined as a physical or operational change in a building, its energy-consuming equipment, …

My Catalyst, Gabrielle Gambino Lyon

Celebration of Learning

Over the course of my internship and shadow program with Pepper Lawson Construction and Ziegler Cooper Architects, I was able to explore the various career paths involved in the design, construction, and civil engineering fields. My work on the construction site of a high-rise apartment building located in the heart of Houston, TX allowed me first-hand experience working and learning alongside project engineers, contractors, building developers, and the construction team.

This project was the perfect confluence of my main areas of interest: structural, mechanical, civil, and environmental engineering, as well as architecture. My daily work consisted of on-site walk throughs, …

Measuring And Evaluating Safety Maturity Of Construction Contractors: Multicriteria Decision-Making Approach, Ali A. Karakhan, Sathyanarayanan Rajendran, John Gambatese, Chukwuma Nnaji

All Faculty Scholarship for the College of the Sciences

Evaluating the safety maturity of construction contractors before awarding the contract is an effective strategy that many owners have started to implement. Given the importance of workplace safety, awarding the contract to safer contractors can enhance project performance outcomes in terms of safety, quality, cost, and schedule. Safety maturity is one quality of a construction organization encompassing interdependent factors that can be used to evaluate expected safety performance. However, there is no formal decision-making framework available in literature that owners can use to evaluate contractor safety maturity. The present study aims to bridge this gap in safety knowledge by proposing …

Implementing Lean Practices In An Academic Department: A Case Study, Ekaterina Koromyslova, Carrie Steinlicht, Teresa J.K. Hall, Albena Yordanova, Byron Garry

Construction and Operations Management Faculty Publications

Lean approaches to continuous improvement, originally practiced and perfected by Toyota Motor Company, have been widely used in the industry sector for many decades. There is a growing trend at universities to adopt lean practices to improve higher education processes. Reduced financial support and growing competition amongst universities and academic programs motivate the implementation of lean practices both at university and department levels.1 Colleges and universities that have adopted lean practices are driven by the need to strategically leverage resources to meet stakeholder expectations, reduce waste or costs, and improve satisfaction with under-performing processes.2 This paper presents an overview of …

Carbon Sequestering Bio Concrete As A Solution To Growing Atmospheric Concentrations Of Co2, Connor Cech, Jackson Walker

Construction Management

High levels of anthropogenic carbon dioxide (CO₂) emissions into the atmosphere are propelling climate change, which has been proven to be highly detrimental to the planet. Cement production for the construction industry is a leading cause of these harmful carbon emissions. This project introduces a potential solution to this issue in the form of a new biological concrete that is treated with carbon sequestering bacteria of the Bacillus family to remove CO₂ from the atmosphere. The consolidated research presented in this project will explain the biology behind this process, and how it can be implemented in construction …

Rail Transportation Of Aggregate Material, Mario Ghilott

Construction Management

Sand, gravel and crushed stone, known as construction aggregates, are the main ingredient in materials to maintaining and building new infrastructure. Construction aggregate has a low cost per ton, but because mass quantities are typically required, if a local source is not available then the cost of transportation quickly exceed the value of the material. The North Bay Area has an estimated 50-year demand of 521 Million Tons (MT) and a current permitted supply of 110 MT. This North Bay Area region has a supply to demand ratio of 21% and is estimated to last 11-20 years (from 2012). This …

Effects Of Tension On Resonant Frequencies Of Strings, Blake Burnett

Senior Theses

This project tests and explores resonance of strings. Since all materials and mechanisms are affected by vibrations, it is important to know the frequencies at which resonance occurs. To explore this subject, strings were used as a model material to test the effect tension has on resonance. The fundamental frequencies and the corresponding modes of resonance were used to analyze the data. The results of this experiment show that increasing tension on a string increases its resonance frequency. Understanding the physics behind resonance frequency allows systems to be designed to take advantage of resonance properties, or to avoid resonance where …

Executive Summary_Feasibility Of Harbor-Wide Barrier Systems: Preliminary Analysis For Boston Harbor, Paul Kirshen

Sustainable Solutions Lab

This report presents a preliminary feasibility assessment of harbor-wide barrier systems designed to protect Boston Harbor from coastal flooding caused by sea level rise (SLR) and storm surges. Conducted by the Sustainable Solutions Lab at the University of Massachusetts Boston and supported by the Boston Green Ribbon Commission, the study evaluates two primary configurations: an Outer Harbor Barrier (OHB) and an Inner Harbor Barrier (IHB). Using hydrodynamic modeling, economic cost-benefit analysis, and social vulnerability assessments, the study finds that while both barrier systems may reduce risk from extreme storm events, they do not mitigate regular tidal flooding without frequent gate …

A Study On Residential Construction Energy Code Compliance In Nebraska, Aaron Thompson

Department of Construction Engineering and Management: Dissertations, Theses, and Student Research

Energy codes are easy to implement, but how effectively are they being followed? To determine energy code compliance of residential construction in Nebraska, a study was conducted in which seven key areas having the most effect on energy savings were analyzed. The study examined both urban and rural areas of the state and compared Nebraska to other states’ energy code compliance studies. The study found an eighty-eight percent average compliance in the key areas. Urban areas tended to be more compliant than rural areas. Nebraska is comparative in energy code compliance to other states. Yet, the state of Nebraska, code …
