Late Morning Concurrent Sessions: Innovations In Aviation Technologies: Presentation: Relative Material Loss: A Methodology For Assessing Island Airport Steel Marine Bulkheads, Robert Ernsting, Constantine M. Koursaris

Aviation / Aeronautics / Aerospace International Research Conference

A July 2015 report from the Airports Council International – North America (ACI-NA) states “U.S. airports are long overdue for [a] major structural improvement projects. Most U.S. airports are aging, … and because of budgetary restrictions, they’re not aging well.”(Garcia and Clampet, 2015). The average US age is 40 years old with the youngest (Denver International) recently turning 20 years old. As airports continue to age, airport commissioners will struggle to find creative ways to either fund airport replacements or extend the service life of existing airport facilities (commonly referred to as service life extension projects or SLEP). Due to …

Specification Recommendation For Use Of High Performance Repair Material, Jennifer Woods

ETD Archive

The State of Ohio and the Ohio Department of Transportation (ODOT) have sought out ways to extend the life of the repair materials used by their construction crews, specifically, using high performance repair materials for the purposes of patching worn down or cracked sections of highways and bridge decks. Ohio is known for its frequent changes in weather, with freeze-thaw cycles occurring multiple times throughout the year. These cycles affect the lifespan of the repair material and create more maintenance for the DOT. Products that combat this problem were chosen, installed and examined over a year period to determine which …

The Behavior Of Simply Supported Plates Under Extreme Shear Loading, Mhd Ammar Hafez

ETD Archive

Steel plates are planar structural elements with one dimension significantly smaller than the others. These elements may fail due to either material yielding or buckling. Buckling is a sudden failure mode, which is not desirable in structural engineering applications. Buckling is called an “elastic buckling” when it happens before material yielding, and is termed as “plastic buckling” if it happens after material yielding. The focus of this thesis is on shear plates, which are plates that are primarily subjected to shear loads. Several studies were conducted to increase the elastic buckling capacity of plates by adding stiffeners to plates. However, …

Decision Making Of Environmental Engineers On Project Selection, Millicent Amanda Davis

Walden Dissertations and Doctoral Studies

Some environmental engineers do not understand how to perceive profitable opportunities in redeveloping the large number of contaminated brownfield sites in New Jersey. The purpose of this qualitative exploratory case study was to find effective decision-making strategies that help environmental engineers acquire profitable environmental redevelopment projects. The target population consisted of 4 environmental engineers in an environmental organization in Camden County, New Jersey who possessed proven decision-making strategies that helped them acquire profitable environmental redevelopment projects in the past 5 years. The conceptual framework for this study was the multiple criteria decision method (MCDM). Semistructured interviews were conducted with the …

ENGR 333

The ENGR-333 class was tasked with answering the question: “What would it take for Calvin College to save $600,000/year on campus operations?” The class choose five buildings as study samples, and invested the saving potential on three aspects: energy efficiency, operational and behavioral changes. The five buildings chose by the class were the: Covenant Fine Arts Center, Kalsbeek Huizinga vanReken, Science Building Complex, Shultze Eldersveld, and Spoelhof Fieldhouse Complex.

Phase I Evaluation Of Selected Concrete Material Models In Ls-Dyna, Bradley J. Winkelbauer

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

Numerous roadside safety systems are configured with reinforced concrete materials, such as bridge railings, median barriers, and roadside parapets. These protective barrier systems are intended to safely contain and redirect errant vehicles as well as prevent impacts into hazardous fixed objects or other geometric features. The analysis and design of these structures may involve impact simulation with finite element software, like LS-DYNA, which includes multiple concrete material models. For such investigations, limited guidance is available for selecting preferred concrete material models and determining appropriate values for specific parameters. This Phase I study investigated the viability and performance of existing concrete …

Learning From Cinara: Exploring The Depths Of Participatory Water Engagement In Cali, Colombia, Zachary T. Strickland

Honors College Theses

Located within the Universidad del Valle in Cali, Colombia, CINARA is an academic institution, comprised of both engineers and social scientists, that has almost three decades of experience regarding participatory approaches to water supply and environmental sanitation. In this paper, I argue that CINARA’s work is important due to its emphasis on meaningful community participation that significantly involves communities in decisions on technical matters that are usually allocated exclusively to “experts.” Furthermore, the valuation of social considerations and non-technical knowledge found amongst CINARA’s engineers stands in distinct contrast to traditional development practices and engineering mindsets. This paper will go on …

ENGR 333

The net-zero homes project that this class worked on throughout the semester was designed to determine what it would take to bring a home in Grand Rapids, Michigan to the status of net-zero and whether or not it is feasible to do so. The idea behind a net-zero home is to reduce the energy usage in the home, whether it is by lifestyle changes, insulation additions, or by appliance upgrades, and then produce the remaining energy deficit from renewable sources, so that the homeowner has a net usage of zero at the end of the year. This report details the …

Where To Park? The East Campus Dilemma, Matthew Lewis

James Madison Undergraduate Research Journal (JMURJ)

James Madison University's East Campus expansion has created parking problems. Student struggle to find a decent parking spot, sacrificing time to park and then perhaps more time to walk to class. This research project seeks answers to the parking problems on the east side of campus, specifically the Festival and Convocation lots. Should students spend time navigating the Festival lot looking for a spot or should they go directly to the Convocation lot? The data and research explain why the latter solution is much more efficient.
