Potentials Of Containers In Creating Modular Architectural Spaces, Karim Al-Khatib, Jinan Makkawi, Ali Kobeissi
Architecture and Planning Journal (APJ)
Containers are currently considered as one of the inventive trends of framing architectural objects. Container architecture is defined as the type of architecture that is characterised by the usage of steel containers as a structural elements and architectural envelope that can be presented as a part of architecture or a function that an activity can happen in it. Due to the specific dimensions that the container has, architects tend to use it to obtain modularity in their projects and the modular design strategies refer to using the containers as a standard unit to carry out the process, these containers are …

Durham School of Architectural Engineering and Construction: Faculty Publications
This paper presents an energy-efficient classification framework that performs human activity recognition (HAR). Typically, HAR classification tasks require a computational platform that includes a processor and memory along with sensors and their interfaces, all of which consume significant power. The presented framework employs microelectromechanical systems (MEMS) based Continuous Time Recurrent Neural Network (CTRNN) to performHAR tasks very efficiently. In a real physical implementation, we show that the MEMS-CTRNN nodes can perform computing while consuming power on a nano-watts scale compared to the micro-watts state-of-the-art hardware. We also confirm that this huge power reduction doesn’t come at the expense of reduced …

Framework To Develop Time- And Voltage-Dependent Building Load Profiles Using Polynomial Load Models, Andrew Parker, Mhd Anas Alkrch, Kevin James, Ahmad Almaghrebi, Mahmoud Alahmad
Durham School of Architectural Engineering and Construction: Faculty Publications
The power consumption of buildings over the course of each minute, hour, day and season plays a major role in how this load influences the Electric Power System voltage and frequency, and vice versa. This consumption is based on the building's load component types, efficiencies, and how they consume power and react to changes in real time. Due to this complexity, standard full-building load models are typically voltage-invariant. This paper proposes a novel framework to transform these voltage-invariant building load models into fully time- and voltage-dependent load profiles using available data on the voltage sensitivity of individual load components. While …

Landscape Architecture and Environmental Planning Faculty Publications
Designers and engineers are developing proposals for physical projects to adapt coastal sites to future sea level rise related threats. This puts pressure on local and regional decision makers to develop strategic frameworks for prioritizing, permitting and funding such projects. However, no systematic evaluation tools exist for the full range of these innovative designs. We build on the literature to develop an evaluation framework that synthesizes two different approaches to categorize these proposals and provide insight for coastal managers and decision makers. We apply this framework to physical projects that address sea level rise in their design around the San …

Evaluating Prediction Models Of Creep And Drying Shrinkage Of Self-Consolidating Concrete Containing Supplementary Cementitious Materials/Fillers, Micheal Asaad, George Morcous
Durham School of Architectural Engineering and Construction: Faculty Publications
Supplementary cementitious materials (SCMs) and fillers play an important role in enhancing the mechanical properties and durability of concrete. SCMs and fillers are commonly used in self-consolidating concrete (SCC) mixtures to also enhance their rheological properties. However, these additives could have significant effects on the viscoelastic properties of concrete. Existing models for predicting creep and drying shrinkage of concrete do not consider the effect of SCM/filler on the predicted values. This study evaluates existing creep and drying shrinkage models, including AASHTO LRFD, ACI209, CEB-FIP MC90-99, B3, and GL2000, for SCC mixtures with different SCMs/fillers. Forty SCC mixtures were proportioned for …

Performance Evaluation Of A Prestressed Belitic Calcium Sulfoaluminate Cement (Bcsa) Concrete Bridge Girder, Nick Markosian, Raed Tawadrous, Mohammad Mastali, Robert J. Thomas, Marc Maguire
Durham School of Architectural Engineering and Construction: Faculty Publications
Belitic calcium sulfoaluminate (BCSA) cement is a sustainable alternative to Portland cement that offers rapid setting characteristics that could accelerate throughput in precast concrete operations. BCSA cements have lower carbon footprint, embodied energy, and natural resource consumption than Portland cement. However, these benefits are not often utilized in structural members due to lack of specifications and perceived logistical challenges. This paper evaluates the performance of a full-scale precast, prestressed voided deck slab bridge girder made with BCSA cement concrete. The rapid-set properties of BCSA cement allowed the initial concrete compressive strength to reach the required 4300 psi release strength at …

Discrete Rigid Block Analysis To Assess Settlement Induced Damage In Unreinforced Masonry Façades, Ryan Ehresman, Nathan Taylor, Bora Pulatsu, Ece Erdogmus
Durham School of Architectural Engineering and Construction: Faculty Publications
In this study, a system of discontinuous rigid blocks is employed to simulate the possible damage mechanisms in unreinforced masonry (URM) façades and load-bearing frame systems subjected to settlement using the discrete element method (DEM). First, the employed modeling strategy is validated utilizing the available experimental results presented in the literature. Once there is a good agreement between the computational models and experimental findings, a sensitivity analysis is performed to quantify the influence of the input parameters defined in the DEM-based numerical model. Finally, the proposed modeling strategy is further utilized to assess the damage pattern that may develop in …

An Architecture Of A New Story, Nathan Y. Lumen
Masters Theses
As the world reckons with an uncertain future at the hands of global climate change and biodiversity loss, the question of how to proceed seems ever more urgent. Approaches to sustainability in design tend to focus on technological solutions to what is often presented as a technical problem. This approach overlooks the ways in which the forces that have led us to this point are born out of our cultural story of what it means to be human, what the natural world is, and what our relationship is to it. This is the story that has permitted if not encouraged …

Detroit: Revitalizing Urban Communities, David N. Fite
Masters Theses
This thesis examines the relationship between architecture and planning in Detroit. The relationship between these two disciplines has reinforced gross inequality in socioeconomic status over many decades. It has been compounded by racism which planning policy and Architecture exploited during the 20th Century for private interests. This impacts the built environment at all scales. Today division is reinforced through small details such as how handrails are placed on benches, but it extends to planning metropolitan areas, and how they are divided up into city and suburb. At the scales between, both architecture and planning reinforce the segregation within their …

The perception that wildfires are completely preventable has caused many structures and communities to be built in locations that will inevitably experience an uncontrollable fire event, risking human lives and infrastructure. Modification of built environments into fire-adapted communities has been explored in this thesis, through multiple strategies. Central to this analysis is the idea that sustainable human developments could adopt a form of biomimicry and indigenous design informed by the adaptions of plants, animals, and native groups that endure and even thrive with regular cycles of fire. This possibility has been assessed through the scope of fire adaptation strategies available …
