A bridge is inserted around the protruding end of the shear connector and a fastener is installed onto the protruding end of the shear connector to engage the bridge and urge the bridge in abutting relation with a lip of the sleeve . The pocket …

The Relationship Between Separated Bicycle Lanes And Bicycle Crashes In Denver, Colorado., Wonsun Chang

Community and Regional Planning Program: Theses and Student Projects

Cyclists feel more comfortable when they ride in a bike facility separated from traffic. Therefore, cyclists tend to prefer separated bicycle lanes over other lanes. It follows that cities are increasing the installation of separated bicycle lanes for bicycle utilization and bicycle safety. However, previous research has proven that separated bicycle lanes cause more crashes. Through empirical study, this paper examined the impact of both separated bicycle facilities and shared roads on bicycle crashes and which is safer or dangerous among methods of the separation. This study deals with bicycle accidents in Denver from 2013 to 2019. This research creates …

Intentionally Unsustainable Forms For Crisis Design: Planned Obsolescence, Daniel Hogan

Architecture Thesis Prep

The ShutDownDC protest that stopped traffic on Monday, September 23rd demonstrated a significant shift in the debate for climate justice. The movement targeted not only the culpable institutions but the physical infrastructures which both monumentalize and enable factors responsible for global climate change (in this case automobile infrastructure). This is a particularly relevant example of how built form not only reflects our cultural preferences for private transportation but also informs/enables the processes which are actively working against public good. In this example, road infrastructure is both a symbol and an active player in the game of continued environmental injustice.

Building A Green Dorm: How Colleges And Universities Across America Have Embraced Sustainable Communal Living, Theresa M. Blickenstaff

Student Publications

Building a dorm is hard work. Building a green, sustainable dorm is doubly so. With their extensive lighting, appliances, heating and cooling needs, fans, and laundry machines, traditional college residence halls are notorious for their large energy footprints. Particularly for colleges such as Gettysburg where dorm living is mandatory for some or all four years, the environmental impact of residence halls is particularly large. As leaders with long histories of inspiring change, colleges and universities in the United States have an obligation to promote sustainable practices. Gettysburg College has announced that in the next few years, it is planning to …

Workforce Development Through Online Experiential Learning For Stem Education, Arefeh Mohammadi, Kevin Grosskopf, John Killingsworth

Durham School of Architectural Engineering and Construction: Faculty Publications

The U.S. workforce is increasingly comprised of older adults, women, and minorities who lack basic skills and are unable to acquire these skills through traditional educational and training programs. New approaches are needed to provide effective training to the adult learner and flexible support for nontraditional students who must balance work-life demands with limited educational opportunities. Contextualized teaching and learning (CTL) is a form of experiential learning that blends both basic skills and occupational training together in environments that allow students to relate subject matter to real-world situations. Virtual CTL environments can be created to better engage students, provide immediate …

This research examined the history, background, and viable solutions to deal with zombie subdivisions in the Teton Valley area (Teton County, Idaho). Overdevelopment, lack of responsible zoning code enforcement and the 2008 economic recession are just some of the key factors that contributed to the ongoing dilemma of zombie subdivisions in the Teton Valley. The current and past long-range plan for Teton County, Idaho was reviewed and analyzed to understand the workings and planning mechanisms that were and are currently set in place. Zoning code, Idaho state statutes and development agreements between Teton County officials and developers, were closely reviewed …

Automated Generation Of Daily Evacuation Paths In 4d Bim, Kyungki Kim, Yong-Cheol Lee

Durham School of Architectural Engineering and Construction: Faculty Publications

Spatial movements of workers and equipment should be carefully planned according to project plans. In particular, it is crucial for workers’ safety to prepare emergency evacuation paths according to changing construction site configurations and construction progress. However, creating evacuation paths for all crews for each day can be an extremely labor-intensive task if it is done manually. Consequently, in most construction projects, evacuation plans are not provided to managers and crews throughout the entire construction. Even state-of-the-art technologies do not suggest ways to generate evacuation paths according to changing progresses presented in 4-Dimensional Building Information Model (4D BIM). This research …

Not Parking Lots But Parks: A Joint Association Of Parks And Transit Stations With Travel Behavior, Keunhyun Park, Dong-Ah Choi, Guang Tian, Reid Ewing

Landscape Architecture and Environmental Planning Faculty Publications

Urban design literature says that public open space in a station area could promote walking and other types of physical activity, enhance place attractiveness, and increase property values. In the context of station areas, however, there is a lack of empirical studies on the relationship between the presence of parks and sustainable travel behavior, which is one of the primary goals of transit-oriented developments (TODs). This study examined the impact of park provision on transit users’ mode choice in three U.S. regions: Atlanta (GA), Boston (MA), and Portland (OR). This study utilized multilevel multinomial logistic regression to account for hierarchical …

Design For Living Complexities, Peter J. Taylor

Working Papers in Critical, Creative and Reflective Practice

Lectures from a 12-session course that addresses the intersection of design with critical thinking. Design in this course means intentionality in construction, which involves a range of materials, a sequence of steps, and principles that inform the choice of materials and the steps. Design also always involves putting people, as well as materials, into place. This happens by working with the known properties of people, as well as the known properties of material, and trying out new arrangements to work around their constraints (at least temporarily). Critical thinking, as I define it, involves understanding ideas and practices better when we …

Architecture Now: A History Of Sustainable Architecture, Meg Vickery

Sustainability Education Resources

As we move further into the 21st century, architects, planners, landscape architects and the general public are increasingly concerned with climate change, environmental degradation, energy and water consumption and the role the built environment plays in contributing to or addressing these issues. Buildings consume almost 40% of the energy used in this country. The way we access buildings, the materials used to construct them, the demands of users within the building all require the earth’s increasingly precious resources. So how did we get here? How did our built environment evolve to require so much energy, water and so many resources? …

Species Diversity And Spatial Pattern Of Old And Precious Trees In Macau, Allen Hao Zhang, Po Ying Lai, Chi Yung Jim

Faculty of Design & Environment (THEi)

The world's fast pace of urbanization has exerted profound pressure on urban trees. With over 400 years of urban history, Macau has developed an exceptionally high population density and ultra-compact mode, yet it permits survival of interesting and diverse heritage trees. These outstanding living remnants connote special values in history, ecology and botany. In conjunction with commemorative importance, they have been designated as Old and Precious Trees (OPT). This study evaluated the OPT with reference to: (a) species diversity and evenness; (b) spatial distribution; (c) tree dimensions, age and health; and (d) spatial differentiation of tree attributes by four districts …

Spatial Differentiation Of Heritage Trees In The Rapidly-Urbanizing City Of Shenzhen, China, Po Ying Lai, Cy Jim, Guang Da Tang, Wen Jun Hong, Hao Zhang

Faculty of Design & Environment (THEi)

In China, heritage trees are actively surveyed and reported. Over 300 relevant published articles were reviewed to assess the contents, trends and geographical distributions of the investigations. The majority of the heritage trees studies in China were found in the eastern provinces and published within 2010–2014. Most studies reported surveys on all old trees. For studies focused on single species, Ginkgo (Ginkgo biloba) and Chinese Yew (Taxus chinensis) was most frequently reported. Unlike the champion tree registry in the US and other countries, the tree registry in China emphasized more on the tree age than the size. We then have …

Efficient Excitation Of Micro/Nano Resonators And Their Higher Order Modes, N. Jaber, M. A. A. Hafiz, S. N. R. Kazmi, M. H. Hasan, F. Alsaleem, S. Ilyas, M. I. Younis

Durham School of Architectural Engineering and Construction: Faculty Publications

We demonstrate a simple and flexible technique to efficiently activate micro/nano-electromechanical systems (MEMS/NEMS) resonators at their fundamental and higher order vibration modes. The method is based on the utilization of the amplified voltage across an inductor, L, of an LC tank resonant circuit to actuate the MEMS/NEMS resonator. By matching the electrical and mechanical resonances, significant amplitude amplification is reported across the resonators terminals. We show experimentally amplitude amplification up to twelve times, which is demonstrated to efficiently excite several vibration modes of a microplate MEMS resonator and the fundamental mode of a NEMS resonator.

Voltage And Deflection Amplification Via Double Resonance Excitation In A Cantilever Microstructure, Mohammad H. Hasan, Fadi Alsaleem, Abdallah Ramini

Durham School of Architectural Engineering and Construction: Faculty Publications

Cantilever electrostatically-actuated resonators show great promise in sensing and actuating applications. However, the electrostatic actuation suffers from high-voltage actuation requirements and high noise low-amplitude signal-outputs which limit its applications. Here, we introduce a mixed-frequency signal for a cantilever-based resonator that triggers its mechanical and electrical resonances simultaneously, to overcome these limitations. A single linear RLC circuit cannot completely capture the response of the resonator under double resonance excitation. Therefore, we develop a coupled mechanical and electrical mathematical linearized model at different operation frequencies and validate this model experimentally. The double-resonance excitation results in a 21 times amplification of the voltage …

Experiencing Extreme Height For The First Time: The Influence Of Height, Self-Judgment Of Fear And A Moving Structural Beam On The Heart Rate And Postural Sway During The Quiet Stance, Mahmoud Habibnezhad, Jay Puckett, M. S. Fardhosseini, Houtan Jebelli, Terry Stentz, L. A. Pratama

Durham School of Architectural Engineering and Construction: Faculty Publications

Falling from elevated surfaces is the main cause of death and injury at construction sites. Based on the Bureau of Labor Statistics (BLS) reports, an average of nearly three workers per day suffer fatal injuries from falling. Studies show that postural instability is the foremost cause of this disproportional falling rate. To study what affects the postural stability of construction workers, we conducted a series of experiments in the virtual reality (VR). Twelve healthy adults—all students at the University of Nebraska-Lincoln—were recruited for this study. During each trial, participants’ heart rates and postural sways were measured as the dependent factors. …

Skip This Chore: Cleaning Your Air Conditioner Condenser Probably Won't Make It Work Better, David Yuill

Durham School of Architectural Engineering and Construction: Faculty Publications

I asked my neighbor who hoses off his air conditioner condenser every spring why he does it. “Because my dad always told me I had to,” he said.

Conventional wisdom like what my neighbor’s dad imparted may always seem right. But through my HVAC scholarship – the study of heating, ventilation and air-conditioning systems – I’ve learned that this particular presumption is probably wrong.

Prediction Of Stress Increase At Ultimate In Unbonded Tendons Using Sparse Principal Component Analysis, Eric Mckinney, Minwoo Chang, Marc Maguire, Yan Sun

Durham School of Architectural Engineering and Construction: Faculty Publications

While internal and external unbonded tendons are widely utilized in concrete structures, an analytical solution for the increase in unbonded tendon stress at ultimate strength, ∆f_ps, is challenging due to the lack of bond between strand and concrete. Moreover, most analysis methods do not provide high correlation due to the limited available test data. The aim of this paper is to use advanced statistical techniques to develop a solution to the unbonded strand stress increase problem, which phenomenological models by themselves have done poorly. In this paper, Principal Component Analysis (PCA), and Sparse Principal Component Analysis (SPCA) …

Durham School of Architectural Engineering and Construction: Faculty Publications

Circumstances exist that call for the aeromedical evacuation high-level containment transport (AE-HLCT) of patients with highly hazardous communicable diseases. A small number of organizations maintain AE-HLCT capabilities, and little is publicly available regarding the practices. The time is ripe for the development of standards and consensus guidelines involving AE-HLCT.

A Practitioner’S Guide To Small Unmanned Aerial Systems For Bridge Inspection, Sattar Dorafshan, Robert J. Thomas, Calvin Coopmans, Marc Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

Small unmanned aerial system(s) (sUAS) are rapidly emerging as a practical means of performing bridge inspections. Under the right condition, sUAS assisted inspections can be safer, faster, and less costly than manned inspections. Many Departments of Transportation in the United States are in the early stages of adopting this emerging technology. However, definitive guidelines for the selection of equipment for various types of bridge inspections or for the possible challenges during sUAS assisted inspections are absent. Given the large investments of time and capital associated with deploying a sUAS assisted bridge inspection program, a synthesis of authors experiences will be …
