Lateral-Torsional Buckling Strength Of Two-Span Glass Fiber Reinforced Polymer Beams, Mojtaba B. Sirjani, Zia Razzaq

Civil & Environmental Engineering Faculty Publications

This paper presents the outcome of a study of two-span glass fiber reinforced polymer (GFRP) I-section beams susceptible to lateral-torsional buckling when subjected to gradually increasing concentrated vertical load(s) in the presence of two different types of lateral bracing schemes. It is found that loading one span results in a smaller buckling load as compared with the cases with loading in both spans regardless of the type of bracing scheme used. Also, the study shows that the addition of midspan braces for the GFRP beams results in up to 5.5 times increase in the buckling load capacity.

Antioch University Dissertations & Theses

The former United Nations Secretary-General Ban Ki-Moon (2014), repeated the core promise in the 1986 UN Declaration on the Right to Development, in which the General Assembly called for an approach guaranteeing meaningful participation of everyone in development and the fair distribution of the benefits of that development. To this end, partnerships are central and can lead to the dignity of the citizens involved as they participate in the development of their own communities. This dissertation research conducted in Manyatta A and B in the Port City of Kisumu, Kenya sought to do just that. The purpose of this study …

Arising: Hurricane (Superstorm) Sandy’S Impact On Design/Planning Professionals, Maxinne R. Leighton

Antioch University Dissertations & Theses

Standing by my bedroom window, looking out at the ocean, a huge wave comes and swallows up my building. Everything around me is gone, including me. I wake up. I am 13 years old and living in the Coney Island Houses on Surf Avenue, Brooklyn, New York. With ongoing anthropogenic changes to the natural environment such as sea level rise and intensifying storms, coastal communities, especially ones segregated by class and culture, are particularly vulnerable in this context that challenges a way of life, and in some instances, threatens that life's survival. This dissertation focuses specifically on what one massive …

Influence Of Bracing On Buckling Strength Of Pultruded Glass Fiber Reinforced Polymer Frames, Mojtaba B. Sirjani, Zia Razzaq

Civil & Environmental Engineering Faculty Publications

A numerical study of the influence of structural bracing on the buckling strength of pultruded Glass Fiber Reinforced Polymer (GFRP) frames is presented. Although the influence of bracing on frames made from other materials such as steel have been studied in the past, this paper investigates the performance of pultruded GFRP portal frames with pinned or fixed column bases. Each frame is constructed with pultruded GFRP I-section members. The influence of I-section column major and minor axis orientation is also investigated. The results demonstrate the practical significance of bracing pultruded GFRP frames. The results show that the buckling loads for …

Multi-Modal Natural Frequency Response Of Utility Transmission Tapered Wood Poles Under Various Soil Foundation Conditions: Natural Frequency Response Under Various Soil Conditions, Ramani Ayakannu, Zia Razzaq

Civil & Environmental Engineering Faculty Publications

Studied herein is the multi-modal natural frequency response of utility transmission tapered wood poles under various soil foundation conditions. Strong winds and hurricanes in various parts of the world have resulted in collapse of such utility poles and have resulted in the disruption of electrical distribution systems in addition to creating hazardous conditions for the public. To avoid the development of resonance under such dynamic loading, the multi-modal natural vibration of the utility poles first needs to be understood in the presence of practical soil foundation conditions. To capture the soil-structure interaction effects on the multi-modal frequencies, a SAP2000 dynamic …

Rethinking Livability In Megacities: Applications Of Jane Jacobs’ Theories On Tokyo And Los Angeles, Kirara Tsutsui

Pomona Senior Theses

This senior thesis in Environmental Analysis compares critical infrastructure pieces in Tokyo and Los Angeles, on three discrete levels, with a particular focus on the pedestrian experience. As global population grows, with more people projected to live in urban cities more than ever, it is critical that we re-evaluate how we think about and “do” city-planning. Following Jane Jacobs’ theoretical framework, this thesis dissects what urban greenspaces, city neighborhoods, and sidewalks look like in LA and Tokyo. It analyzes, for each proxy, how two of the world’s most “developed” and largest cities have developed into the current landscape. Historical, cultural, …

Re-Imagining Nature In Dense, High Rise Urban Environment: The Present And Future Of Green Building Infrastructure In Singapore, Claire Yi

Pomona Senior Theses

From the futuristic Jewel at Changi Airport, the healing gardens at Khoo Teck Puat Hospital in Yishun to School of the Arts at Orchard Road, greenery has sprouted in buildings vertically and horizontally in Singapore, painting a growing green canopy for the dense, high rise city. This paper combines both analyses from first-hand site visits and case studies from external scholar studies to examine the performance of existing Green Building Infrastructures (BGIs) within Singapore’s unique urban context. The study reveals that the success of BGIs is highly dependent on the programming (i.e. thermal comfort design, accessibility, amenity facilities etc.), as …

The Living Community Challenge: An Uncase Study In Biophilic Master Planning, Jordan Grimaldi

Pomona Senior Theses

In a world that is quickly urbanizing with a climate that is rapidly changing, the International Living Future Institute’s (ILFI) Living Community Challenge (LCC) offers a whimsical yet highly relevant model for sustainable development—creating cities that are as connected and beautiful as forests. As no certified Living Community exists yet, this thesis serves as an “uncase study” of North Rainier, a neighborhood in Seattle that has registered for the Challenge. In an effort to assess the LCC’s perceived effectiveness as a model for sustainable development, this thesis first summarizes nearly 400 centuries of U.S. developmental history to give greater context …

Remembering The City: An Augmented Reality Reconstruction Of Memory, Power, And Identity In Ho Chi Minh City Through Cartography & Architecture, Thuy Dinh

Senior Independent Study Theses

Cartography and architecture are official channels that facilitate remembrance in Ho Chi Minh City. Maps and buildings serve as sites for actors of memory to manipulate the city's narratives and shape its collective identity. Power enables the production of space and knowledge through sites of memory. The ruling regimes of Ho Chi Minh City have leveraged control over the natural environment and the local population to create new forms of materials that propagate their ideologies and ideals for the city. Alterations to the natural and built environments in the city legitimize the authorities' official narratives for its history and future …

Foster Rhodes Jackson And The Visual Conquest Of The West, Eve Kaufman

Scripps Senior Theses

Colonizers settled the Los Angeles and the Southern California region in part by using Modernism’s visual rhetoric and propagandic implications during the time of suburban sprawl. Suburban sprawl refers to the mass single family home development which took place from the 1920^[1]s until now but peaked from the 1970s to the 1990s. Los Angeles sprawl grew particularly in the 1950^[2]s as soldiers returned from WWII. It was a way for middle class white families to accrue generational wealth and follow through on the American Dream^[3].

The primary result however disenfranchised already marginalized groups. This …

Unaccepted Streets In Bayview Hunters Point: Addressing Spatial Injustice Through Public Open Space, Clare Blackwell

Scripps Senior Theses

Bayview Hunters Point is at the epicenter of environmental justice issues in San Francisco. The district has historically been the location of the city’s most polluting industries, as well as some of its poorest residents and its greatest concentration of public housing. As the city’s zoning developed over the twentieth century, the southeastern neighborhood on the bay became a patchwork of industrial and residential parcels of land, fueling spatial injustice, in particular a lack of access to public open space.

Increasing greenspace would likely address spatial injustice in Bayview Hunters Point. However, green gentrification–the consequence of resident displacement as a …

Uniting Maternity Care With Neonatal Intensive Care: Analysis Advancing Hospital Experiences For Families Of Newborns Through Design, Stephanie Legg

Master's Theses and Doctoral Dissertations

The landscape of childbirth has changed immensely over the last century. Medical intervention has surpassed the needs of mother and infant to be together when either requires medical attention. By bringing medical equipment for both into a single hospital room, separation between the two will be decreased. For this study, mothers of infants admitted to neonatal intensive care were questioned with a mix-methods survey to discover what challenges they faced in order to amend the built environment to increase their satisfaction with their hospital and post-birth experience. Mothers showed less ability to interact with their infants when medical needs were …

An Experiential Online Training Approach For Underrepresented Engineering And Technology Students, Arefeh Mohammadi, Kevin Grosskopf, John Killingsworth

Durham School of Architectural Engineering and Construction: Faculty Publications

Workforce pipelines are essential to sustain a productive workforce in an increasingly competitive, high-tech environment. Advanced automation, sensors, materials and data analytics will increase the need for highly skilled workers in the manufacturing (and manufactured construction) sector. Attracting and developing the next-generation workforce is not without its challenges; however, students are often deficient in technical skills and generally have negative perceptions about manufacturing and construction. As a result, new education and training models have been developed to provide instruction at all levels of the educational system, with a focus on both traditional students and non-traditional students, including ethnic minorities, women, …

The Magic And Metaphysics Of Shit :The Production Of Space And Digital Technology, David Capener

Articles

Reading Henri Lefebvre alongside Bernard Stiegler, this paper explores the changes that have taken place to the production of space in our age of digital technology. Lefebvre sensed the radical changes taking place in society through the implementation of computational technologies. He asked a prescient question: How is this space being produced? Lefebvre was unable to foresee the significant changes to the actual mechanics of the production of space brought about by the third industrial revolution. A thinker who does do this is Bernard Stiegler who is interested in how new digital technologies change memory via tertiary mnemotechnical devices – …

School: A Community And Environmental Resource, Samantha M. Kelley

Architecture Theses and Projects

Schools play an important role in the lives of children, and can play a larger role in the broader community. Throughout history, schools have existed that have been connected to the environment, whether it was to simply provide children with the opportunity to spend time outside, or to teach students about the natural world. With the state of climate change that exists today, connecting students to the environment is of utmost importance. Students must understand the environment, in order to appropriately understand the threat of climate change, and ultimately take action to combat it.

Schools are an ideal location to …

Live, Work, Unite: Housing And Workspaces For Providence Artists, Michael J. Kelly

Architecture Theses and Projects

The objective of communal architecture in society is not only to serve people’s basic spatial needs, but also improve their knowledge about the importance of sharing the gift of space itself, even if it is designed for two different purposes. This project focuses on all that stands between the two most basic purposes of a space: living and working. In more ways than one, those two activities are not so different. However, that depends on the occupation. In some fields of work, offices share common spatial features with dwellings. But on the other hand, they are often too different and …
