Designing For Micropolitan Areas: A Public Library Design Manual For Adaptive And Circular Applications, Samantha R. Zeek

Masters in Architecture Program: Theses

A micropolitan statistical area refers to a geographic region in the United States that has at least one urban cluster of population between 10,000 and 50,000 people, as defined by the US Census Bureau. According to the 2019 Fiscal Year Public Libraries Survey, more than three-fourths of public libraries serve areas with fewer than 25,000 people in the U.S. (Frehill, et al. 2021). However, as new design techniques and advanced services are developed, they tend to be primarily implemented in libraries serving metropolitan areas, which only serve around a quarter of the US population, leading to an unequal distribution of …

Designing The American Dreamscape: Suburbs Of Worship And The American Dream, Rebecca Virgl

Masters in Architecture Program: Theses

This thesis explores suburbia as the physical manifestation of the American Dream as a pseudo-religious system. This religious system and contemporary suburban ideology are explained and disseminated through a historical review and analysis of suburban media. Pop culture serves as a signpost that directs public opinion and cultural value; much of media today wrestles with the ideas of the American Dream, fore fronting these cultural values in our collective identity. Once the baseline of socio-economic religious ideology has been established in the American Dream, the extremes of these beliefs were explored in three suburban environments: home, labor, and retail. Each …

Sustainability Of Form-Based Zoning Codes In An Existing Suburb, Elvira Batelaan

Community and Regional Planning Program: Professional Projects

Most planners and architects agree that the current rate of growth and sprawl in American cities is not sustainable. This thesis will explore how form-based zoning codes can be used to implement policies that increase the sustainability of an existing suburb. Typically, form-based zoning codes are applied to either new subdivisions in a city or to an overlay district in a city which does not get to the heart of the issue. A solution is needed for the rest of the city, such as downtown, industrial areas and existing suburbs, to further increase the sustainability of the entire city. In …

Reconfigurable Metatiles With Circular Maze-Like Space-Coiling-Based Acoustic Metastructure For Low-To-Mid Frequency Sound Attenuation, Sanjay Kumar, Heow Pueh Lee

Durham School of Architectural Engineering and Construction: Faculty Publications

This study presents a compact, lightweight, and reconfigurable acoustic metatile for sound mitigation applications. The metatile prototype is designed based on a circular maze-like acoustic metastructure, which utilizes a space-coiling technique for enhanced acoustic performance in low-to-mid frequencies. The proposed labyrinthine acoustic metadisk structure comprises a central hollow front face sheet and two coiling-up backing cavities. Experimental results show that the metadisk has high absorption peaks of 0.81 and 0.75 at 574 and 1436 Hz, respectively, and exhibits high sound transmission loss (STL) values (≥25 dB) in separate wide frequency bands between 100–580 Hz and 820–1600 Hz. Based on the …

Structural Testing Of Concrete Walls On-Edge With Combined Axial And Out-Of-Plane Loading, Salam Al-Rubaye, Marc Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

Full-scale testing of structural components can be time consuming and difficult. The design of full- scale slender concrete walls is highly influenced and controlled by second-order and out-of-plane bending loads. Previous experiments on out-plane bending of slender walls and insulated walls have been performed with bending in the direction of gravity (with or against). Additionally, most of the research considering out-of-plane bending does not include an axial load and suffers from inaccurate results due to not simulating the actual loading and constraining conditions or safety issues. This testing method was developed expressly for the determination of slender wall behavior in …

Impact Of The Pandemic On Computer Science Education, Dwight Miller, Guy Trainin

Research and Evaluation in Education, Technology, Art, and Design

This poster examines the impacts of the Covid-19 pandemic on computer science education in Nebraska. Data collected by Code.org on student and teacher engagement in CS education in Nebraska public and private schools helps paint a picture of the changing landscape.We reveal a significant decrease in rural student participation since the 2019-20 school year, a minimal increase in the number of teachers teaching with Code.org, and a significant drop in participation of girls at the secondary level. By uncovering these trends in engagement, we hope to inform and inspire educators and administrators to take action.

Design Of Wythe Connectors For Concentrated Out-Of-Plane Loading Of Insulated Walls, Ammar Al-Maabreh, Fray F. Pozo, Marc Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

Partially composite concrete insulated wall panels must be designed to handle different types of loading, including out-of-plane concentrated loads. Currently, there is a lack of information that describes and helps engineers analyze the mechanics of axial load transfer for insulated wall panels for concentrated out-of-plane loads that may occur from lifting, handling, or floor/roof reactions. Such loading generates axial and shear forces in the wythe connectors, making it important to choose the type and quantity of connectors in the design process. This paper aims to develop a better understanding of out-of-plane point load mechanics on concrete sandwich wall panels. A …

Inter-Wythe Slip Design Criteria For Non-Composite Insulated Walls, Abdelrahman Awawdeh, Fray F. Pozo-Lora, Marc Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

Non-composite insulated wall connector design is governed by ICC-ES AC320. This standard works entirely in the loading domain, asking the engineer to prevent connector failure due to tension and shear loading. In this paper, the authors discuss additional criteria related to thermal loading and out-of-plane wind loading that create displacement demand in the non-composite connectors. Loads suitable for such analyses are not well defined. Loads are assumed and demonstrated herein and shown to cause significant displacement demand on connectors. Limited non-composite wythe connector testing is available, and some results are presented here. A comparison indicates that outright failure of non-composite …

Thus, in order to determine the estimated steel savings of this system as compared to the moment and braced frames, the four-story and eight-story buildings that are 96' × 96' in the plane and utilize …

Architecture And New Urbanism’S Relationship To Biomimicry And Floral Design, Alycia Timmerman

Honors Theses

The craft of floral design is classified as an art and a science. Similarly, architecture is rooted in the two disciplines. After conducting research and exploring biomimicry through the design process, it became evident that the process of design for architecture and floral design are similar. This relationship can also be extended into the field of planning and the New Urbanism movement. This study explores the integration of floral design and biomimicry with architecture and New Urbanism at the scale of the building and city block.

Airborne Infection Risks From Covid-19 In Meat Processing Plants And Different Solutions To Mitigate The Risks, Debayan Shom

Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research

Meat processing plants are linked to the rapid spread of COVID-19 cases. A related literature review shows a lack of proper ventilation standards for the meat processing plants for workers’ health and safety. Ventilation rates in these plants are considered adequate if the meat products are unadulterated. Thus, the air distribution and ventilation rate experiments were conducted in three meat processing plants. These measured ventilation rates were either compared to ASHRAE Std. 62.1 (2019) for a similar space or the design values provided by the plant’s administration. The measured values were low in common spaces, such as the cafeteria and …

A Framework To Predict Variability Characteristics In Building Load Profiles, Sam Moayedi, Andrew Parker, Kevin James, Xiaoyue Cheng, Michael Hempel, Hamid Sharif, Mahmoud A. Alahmad

Durham School of Architectural Engineering and Construction: Faculty Publications

The expansion of Advanced Metering Infrastructure (AMI) has provided building operators and researchers detailed information on building energy consumption. The majority of AMI systems, however, record data at relatively low resolutions of 15, 30, or 60 minutes, due to cost, storage and bandwidth limitations. Emerging applications in power flow analysis, Quasi-Static Time-Series Simulation (QSTS), smart grid integration and load matching, however, require data at higher resolutions. Short-term energy demand can deviate significantly from long-term averages, with an unknown magnitude and frequency when only low-resolution load profile data is available. This paper presents a novel data-driven approach to predict characteristics of …

Integration Of Real-Time Semantic Building Map Updating With Adaptive Monte Carlo Localization (Amcl) For Robust Indoor Mobile Robot Localization, Matthew Peavy, Pileun Kim, Hafiz Oyediran, Kyungki Kim

Durham School of Architectural Engineering and Construction: Faculty Publications

A robot can accurately localize itself and navigate in an indoor environment based on information about the operating environment, often called a world or a map. While typical maps describe structural layouts of buildings, the accuracy of localization is significantly affected by nonstructural building elements and common items, such as doors, appliances, and furniture. This study enhances the robustness and accuracy of indoor robot localization by dynamically updating the semantic building map with non-structural elements detected by sensors. We propose modified Adaptive Monte Carlo Localization (AMCL), integrating object recognition and map updating into the traditional probabilistic localization. With the proposed …

Machine Learning Approach For Automated Detection Of Irregular Walking Surfaces For Walkability Assessment With Wearable Sensor, Hui R. Ng, Isidore Sossa, Yunwoo Nam, Jong-Hoon Youn

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The walkability of a neighborhood impacts public health and leads to economic and environmental benefits. The condition of sidewalks is a significant indicator of a walkable neighborhood as it supports and encourages pedestrian travel and physical activity. However, common sidewalk assessment practices are subjective, inefficient, and ineffective. Current alternate methods for objective and automated assessment of sidewalk surfaces do not consider pedestrians’ physiological responses. We developed a novel classification framework for the detection of irregular walking surfaces that uses a machine learning approach to analyze gait parameters extracted from a single wearable accelerometer. We also identified the most suitable location …
