Abstract:

There is a consistent housing crisis that is affecting our society today. Nearly 582,462 are homeless alone in the United States, with San Diego having the 4th highest unhoused population in the country (Hud, 2022). My research this summer seeked to understand the current living conditions of low-income families within our local community, with an emphasis on the El Cajon neighborhood in the Eastern part of San Diego County, and develop new architectural designs for sustainable and affordable housing. Through this lens I was able to see how a class in society just above homelessness lives day to day …

Daunting Encounters: La Hague’S Infrastructures Of Secrecy, Agnes Villette

Secrecy and Society

The article explores secrecy, more particularly, nuclear secrecy in relation to two nuclear facilities situated at the tip of the Norman peninsula of La Hague, in France. Both sites - the CSM nuclear waste repository and the close-by refueling plant - were developed at the end of the 1960s in connection with France’s extensive civil and military nuclear program. While institutional archives and access to the sites remain tedious, the article contends that the nuclear secrecy shielding the facilities can be approached by unpacking the numerous accidents that took place at the site. Silenced and subjected to amnesia, spills and …

Designing Affordable And Sustainable Apartments, Jaziel Mayoral, Juliana Maxim

McNair Summer Research Program

One of the policies created in California to address the issue of unaffordable housing is the density bonus law, which incentivizes construction of more affordable housing. However, this policy can be difficult to understand and construction is one of the main sources of pollution, which is why it is essential to design new buildings to minimize damage to the environment and people, so in this project we test the density bonus law on a real site in El Cajon while trying to reduce pollution with the use of passive design and natural materials. I analyzed the design methods of successful …

Behavior Of Ultrahigh-Performance Concrete Plates Encasing Steel H-Piles, Mohamed Elgawady, Binod Shrestha

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Steel H-piles are exposed during their service life to wet-dry cycles in combination with salts, such as deicing, that may result in corrosion, leading to cross-sectional loss and reduction in axial load-carrying capacity. This paper proposes an innovative repair method for corroded steel H-piles using ultrahigh-performance concrete (UHPC) plates. The UHPC plates are reinforced with carbon fiber-reinforced polymer (CFRP) grids. The UHPC plates bridge the corroded segment so that the axial force bypasses the corroded segment. The UHPC are bolted to the steel H-pile using high-strength bolt connectors (HSBCs). Eleven steel H-piles bolted with UHPC plates were investigated experimentally under …

Reflecting On Design: A Study Of The Relationship Between Beginning Landscape Architecture Students’ Graphic Skills And Self-Efficacy Through Hybrid Assessments And Reflective Writing, Rachel Michelle Nobles

Theses and Dissertations

The purpose of this study is to examine the connection between self-efficacy, reflective writing, and graphic quality inside a first-year Landscape Architecture design studio. Reflective writing and self-efficacy can be studied to better understand how to motivate students within a design studio. Bandura (1977) defines self-efficacy as the belief in one’s own capabilities relating to motivation, behavior, and environment. Reflective writing is overlooked as a mode of advancing knowledge in the design process (Lousberg, 2019). The data were collected with pre- and post-semester Likert scale questionnaires, graphic skill-building tests, and reflective writing. To determine growth, the pre-and post-Likert-type questionnaires and …

Effect Of Competitive Adsorption Between Specialty Admixtures And Superplasticizer On Structural Build-Up And Hardened Property Of Mortar Phase Of Ultra-High-Performance Concrete, Le Teng, Jingjie Wei, Kamal Khayat, Joseph J. Assaad

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study aims to enhance structural build-up of ultra-high-performance concrete (UHPC) without influencing the initial flowability, which is critical in repair applications (e.g., use of UHPC in thin bonded overlays for bridge deck rehabilitation). Specialty admixtures, such as a viscosity-modifying admixture (VMA), have been used to enhance the structural build-up at rest. However, the use of specialty admixtures can increase superplasticizer (SP) demand to maintain proper flowability; the synergistic effect of these admixtures on structural build-up is not well understood as the coupled admixture content can reverse the net effect on yield stress, viscosity, and thixotropy. In this study, VMAs …

Postwar Cooperative Housing: On The Historical And Community Significance Of South Dahlia Lane, John Boydstun

Architecture and Planning ETDs

American cities after WWII including Denver experienced a boom in population resulting in a shortage of affordable housing. One innovative response to the demand for affordable housing was the formation of the Mile High Housing Association (MHHA), a Colorado non-profit organization founded in 1948 by four University of Denver professors. The MHHA was Colorado’s first housing cooperative and founded on the ideals of a supportive and collaborative community. MHHA’s goals included providing affordable single-family homes with a new modernist design and a neighborhood site plan that supported a cooperative lifestyle. Backed by new legislation in 1948 for FHA financing, the …

Bringing Vanished Landscapes To The Surface: A Multi-Tool Approach To Unearthing Charleston's Walled City, Alexis Allen

All Theses

The early 18^th century historic fortification system that surrounded the urban town of Charleston has been a focus of excavations and historical research within the past two decades. However, while the outline of early Charleston’s walled city is hypothesized through the analysis of historic maps and plats, very few fortification locations have been visually confirmed. In order to determine their accuracy, this thesis georeferenced eleven historic maps and four plats to the modern landscape. As a result, possible locations of Charleston’s walled city were predicted. These were surveyed as test sites and remote sensing methods were employed that helped …
