Multidimensional Dialogue Through Architecture | An Exploration Of The Possible Dialogue Between Humans And Walls, Fengqi Li

Architecture Senior Theses

This thesis proposes that architectural design no longer has to be primarily static, but rather it can be dynamically responsive to multiple information streams and conditions.

Multidimensional Dialogue Through Architecture is developed from the understanding of human factors and ergonomics. The dispersed works on research and inference are different ways to explore the interaction between the discipline of architecture and the other fields, such as psychology, engineering, bio-mechanics, physiology, cognitive science, and anthropomorphic. Therefore, the purpose of this thesis is not to design a specific building that works perfectly in particular conditions but rather to use architectural elements to mediate …

The Renaissance Of The Railway | Towards A Global High-Speed System, Xiaoyu Li

Architecture Senior Theses

The railway has shown its unique character as a mode of transportation since its invention in Europe during the Industrial Revolution. In the beginning, its carrying capacity made it stand out, transforming human behavior, and stimulating economic productivity. During the 20th century, air travel, the railways, and long-distance road networks have shared the burden of human transportation - in many countries the car and plane have won out. In recent decade, however, new interest in the railway's potential has been generated as a result of the emergence of new technologies like high-speed rail and the maglev system. Greater speeds are …

The Burning Building | Fire As Place, Winnie Tu

Architecture Senior Theses

The importance of fire in human social evolution is widely acknowledged but the extent of its impact is not fully explored. Generally, it is connected to energy, light, purification, illumination, creation, destruction and metamorphosis. Fire’s paradoxical nature has built up many societies throughout human history and has been the primary social driver within communities. Due to technological advances, its energy has been transformed into a distant element which is being used discretely in industrial buildings, hidden under basements, or replaced by other forms of energy. Now, heat, energy, and light is readily available anywhere at any time, eliminating the biological …

Innie/Outie | Renegotiating Figure And Structure, Maxwell Rosner

Architecture Senior Theses

This thesis contends that in order to sustain its claim to be socially progressive and accessible enterprise, the discipline of architecture must resist the divorce of figure and structure.

Innie/Outie considers Architecture as a simultaneously typological and teleological proposition. Architects exploit typology as a means of classifying, diagramming, and ultimately flattening and iconicizing ideas about Architecture so as to place them within a broader cultural context, thereby making them intellectually accessible to their audiences. By contrast, architects from the advent of Modernism onwards have displayed a critical preoccupation with the discipline’s teleological potential, the creation of form that follows function …

Subtraction | Construction In Reverse, Sherina S. Zhang

Architecture Senior Theses

The life of a building does not begin at the creation of the new; it starts with the subtraction of the old. As the pace of technological development accelerates, buildings are erected and demolished at an unprecedented rate. Cities use their urban artifacts like skyscrapers, to portray economic and political prowess. For example, the ghost cities of China are relics of a burst financial bubble while Venezuelan ruling party elites name business towers after themselves as a show of power and prosperity. Many parts of the world today are now overbuilt with artifacts that decline into obsolescence. Demolition procedures erase …

Two Lands, One System | Redefining The Border Crossing, Matthew Trulli

Architecture Senior Theses

The Israeli and Palestinian populations each have their own distinct infrastructural system, which operates independently and fails to connect the people in this region. This thesis contends that if a two-state solution is implemented under the guidelines of the 2003 Geneva Accord, new connections can stitch the populations of Israel and Palestine together through a reimagined border system.

These divisive infrastructural networks, which are a result of tense relationships, have also sparked increased violence throughout the region, particularly in Jerusalem. The French Hill, located north of the Old City in Jerusalem, is positioned at a critical point in the infrastructural …

The Seed | Urban Vertical Farming Germinated, Michael Lima

Architecture Senior Theses

A city works as an ecosystem in many ways. However, we currently do not live within that ecosystem, as the difference between an ecosystem and a city is the waste output and food input . Nature and society do not exist independently because there are no spaces of nature unaffected by man. With this in mind we need to reestablish our relationship with nature. Architecture and engineering can be used to create buildings that will allow humans to turn cities into ecosystems. This thesis argues that Urban Vertical Farms will produce social and economic hubs that will be a new …

The training facility would educate the locals how to build safer structures that would be more effective during earthquakes.

The focus of this report is to elaborate on the process of the project, the difficulties encountered, and the benefits of the overall project when completed.

Free Encounters | Giving Form To The Informal Workplace, Ryan Williams

Architecture Senior Theses

This thesis contends that the "office" as a solely economic construct is no more: Its utility as an engine driving productivity and the accumulation of capital has stalled in our present age of information where value is constructed through knowledge exchange and interaction.

Via the use of new technologies, millennial workers' transition from the college campus to the office has become more seamless and, this thesis argues, it is in this paradigm shift that it is possible to identify a blurring of the public and private spheres. The millennial worker-turned-freelancer's life exists forever suspended between work and play, place and …

Uncreative Construction | Domestic Mutations In America, Sean Morgan

Architecture Senior Theses

A shift in residential patterns in American cities have fostered a breeding ground for mutant buildings. Owners split, manipulate, and expand their houses as they create idiosyncratic constructs of great visual and spatial complexity. Originally developed for a middle class population, single-family homes have become mixed-use or multi-family complexes thanks to the resourceful implementation of commercial materials.

This thesis aims to develop a new strategy for transforming the normative American house by using the conventions of platform frame construction. Variations will emerge from a set of design constraints, which—unlike that employed for typical houses—are based on data that disregards style …

Effects Of Noise, Reverberation And Foreign Accent On Native And Non-Native Listeners’ Performance Of English Speech Comprehension, Zhao Ellen Peng, Lily M. Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

A large number of non-native English speakers may be found in American classrooms, both as listeners and talkers. Little is known about how this population comprehends speech in realistic adverse acoustical conditions. A study was conducted to investigate the effects of background noise level (BNL), reverberation time (RT), and talker foreign accent on native and non-native listeners' speech comprehension, while controlling for English language abilities. A total of 115 adult listeners completed comprehension tasks under 15 acoustic conditions: three BNLs (RC-30, RC-40, and RC-50) and five RTs (from 0.4 to 1.2 s). Fifty-six listeners were tested with speech from native …

Design And Optimization Of Membrane-Type Acoustic Metamaterials, Matthew G. Blevins

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

One of the most common problems in noise control is the attenuation of low frequency noise. Typical solutions require barriers with high density and/or thickness. Membrane-type acoustic metamaterials are a novel type of engineered material capable of high low-frequency transmission loss despite their small thickness and light weight. These materials are ideally suited to applications with strict size and weight limitations such as aircraft, automobiles, and buildings. The transmission loss profile can be manipulated by changing the micro-level substructure, stacking multiple unit cells, or by creating multi-celled arrays. To date, analysis has focused primarily on experimental studies in plane-wave tubes …

The Enclaving Of Dubai: An Investigation Of The Factors Governing The Emergence And Spreading Of The Gated Residential Communities In The City, Mahmoud Saeed Al Mansi

Theses

This study attempts to fill a gap within the current existing literature of the worldwide phenomenon of rise and spread of walled communities. The study primarily examines the factors relating to gated residential communities in Dubai, a city that is not covered in the literature of the subject. Specifically, it traces the emergence of gated residential communities in the urban history of Dubai, investigates their magnitude over time, locates them within the city, and investigates the various factors affecting their spread, particularly in the past few decades. To achieve these objectives, a field survey and a qualitative research were conducted …

Towards A Localized Form-Based Code For Abu Dhabi Urban Neighborhoods, Arwa Khalid Sabri

Theses

Form-Based Code (FBC) is a sustainable planning tool that helps realize sustainable urban form and sustainable communities from different perspectives, including mixing of land uses, diversifying housing types, achieving walkability and cycling as well as permitting community involvement in decision making and design processes. It is therefore considered as a comprehensive tool that regulates different planning scales from master plan to individual buildings. Locally, Abu Dhabi Emirate lacks a FBC that could help achieve its sustainability-orientated 2030 vision and thus promote its envisaged sustainable urban identity. This research aims at studying to what extent the present form-related standards and guidelines …

Private Room Of The Wheel | A New Form Of Transient Dwelling, Kathy Teng

Architecture Senior Theses

The cross-country highway and road trip are deeply rooted in the American psyche, supported by the rapid growth in ownership of automobiles by American families since the 1940s, establishing a sense of freedom and leisure in their mobile lifestyles. However, other highway users have less control and freedom over their daily routine. These users are part of a vast network of international commerce reliant on the long haul.

The time long-haul truck drivers are away from home is prolonged, with the end of each day spent sleeping in fixed truck cabins and eating at banal truck stops. “ ‘I can …

Never-Land | A Parasitic And Accumulative Approach To Urbanization In China, Xiaoyan Dong

Architecture Senior Theses

Ever since 1960s, European situationist and Japanese metabolist architects constantly reject the uniformity and totalitarian of modern architecture/urban design, seeking parasitic and dynamic approaches to post-war urbanization. Projects such as the Plug-In City and the Tokyo Bay dream of alternative urban scenarios by reversing traditional perceptions of infrastructure’s role in the city, combining architecture, technology and society together. However, these megastructure projects not only neglect the existing urban context but also lack political and economic driving force. As a result, they are considered utopian by many contemporary critics.

Fifty years later in China, fast urbanization process creates problems for both …

Algorithmic Settlements | Modeling Informal Settlement Through Automated Generative Design, Ben Anderson-Nelson

Architecture Senior Theses

The position of the architect when designing is to arbitrate which information is relevant and which is not, and to do so across a broad spectrum of fields. Considering this, Christopher Alexander claimed as long ago as 1964, that “design problems are reaching insoluble levels of complexity.”This thesis focuses on informal settlement growth and how architects can investigate growth as a part of master-planning new housing. Drawing on case studies of settlements, video game logics, and existing architectural tools, a tool was developed to study the growth of settlements. This tool is based on cellular automata, a spatial and algorithmic …

The Effects Of Tones In Noise On Human Annoyance And Performance, Joonhee Lee

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

Building mechanical equipment often generates prominent tones because most systems include rotating parts like fans and pumps. These tonal noises can cause unpleasant user experiences in spaces and, in turn, lead to increased complaints by building occupants. Currently, architectural engineers can apply the noise criteria guidelines in standards or publications to achieve acceptable noise conditions for assorted types of spaces. However, these criteria do not apply well if the noise contains perceptible tones. The annoyance thresholds experienced by the general population with regards to the degree of tones in noise is a significant piece of knowledge that has not been …

Model For Coupled Large Strain Consolidation And Solute Transport In Layered Soils, Hefu Pu, Patrick J. Fox

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A numerical model, called CST3 (Consolidation and Solute Transport 3), is presented for coupled one-dimensional large strain consolidation and solute transport in layered soils. The consolidation algorithm accounts for vertical strain, soil self-weight, general constitutive relationships, relative velocity of fluid and solid phases, changing compressibility and hydraulic conductivity during consolidation, unload/reload, time-dependent loading and boundary conditions, external hydraulic gradient, variable preconsolidation stress profiles, and multiple soil layers with different material properties. The solute transport algorithm accounts for advection, diffusion, mechanical dispersion, linear and nonlinear sorption, equilibrium and nonequilibrium sorption, porosity-dependent effective diffusion coefficient, and first-order decay reactions. CST3 is based …

Post-Repair Seismic Assessment Of Rc Bridges Damaged With Fractured Column Bars - A Numerical Approach, Ruili He, Yang Yang, Lesley H. Sneed

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Seismic repair of reinforced concrete (RC) bridge columns has been studied extensively during the past several decades; however, few studies have been conducted on the influence of the column repair (member level) on the post-repair performance of bridge structures (system level). In a previous experimental study by the authors, a method was developed to rapidly repair severely damaged RC bridge columns to enable the quick reopening of the bridge to emergency traffic. Thus, a lower limit state was used for the repair design, so that the lateral strength and drift capacity of a repaired RC column with fractured longitudinal bars …

Strain-Controlled Cyclic Simple Shear Tests On Sand With Radial Strain Measurements, Xin Kang, Louis Ge, Kuang Tsung Chang, Annie On Lei Kwok

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Strain-controlled cyclic simple-shear tests were performed on silica sand with radial strain measurements. The specimens were tested under a constant K0 condition and subjected to cyclic loading and post cyclic monotonic loading. Threshold cyclic shear strain, volumetric strain, secant shear modulus, and damping ratio are investigated. Generally, the volumetric strain behavior in this study agreed well with literature findings that were investigated using the conventional cyclic direct simple shear test (without radial constraints). Radial strain during monotonic simple shear (post cyclic loading) was found to be a good parameter in monitoring the onset of flow slide in cohesionless soil. The …

Quantification Of Time Varying Directivity Of Musical Instruments, Madeline A. Davidson

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

Static directivity patterns of musical instruments have been mapped somewhat extensively, but little research has been done in analyzing the directivity patterns of musical instruments over time as they play. Directivity patterns can be affected by variables such as instrument, frequency, dynamics, and style. This thesis proposes a set of quantification methods of time varying directivity, all derived from the maximum Directivity Index analyzed at consecutive short-duration time windows comprising the musical excerpt. The instrumental recordings used in this paper are taken in an anechoic chamber using either a 5, 13, or 32 multichannel setup. From the values of maximum …

Theses

In order to decrease the reliance on oil and create more economic opportunities, the UAE has witnessed a development boom over the last few decades in an effort to promote tourism. Dubai specifically has purposefully undergone dramatic architectural evolutions with the aim of transforming the city into a tourist hub and a global attraction. Over the last few years, iconic buildings including Burj Al Arab and Burj Khalifa have been built at different times to become prominent landmarks that promote the city’s global image and combine traditional/local elements in such a way as to form completely new unrecognizable forms i.e. …

Evaluation Of Carbonation Resistance Of Paint Coated Concrete For Buildings, Tommy Y. Lo, Wenyu Liao, C. K. Wong, Waiching Tang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

When evaluating the carbonation resistance of paint coated concrete, the effects of both the strength grade and the curing conditions (standard curing and accelerated curing) of concrete substrate on carbonation resistance of paint coated concrete were investigated. The concept of the carbonation suppression ratio of paint was presented for evaluation of the anti-carbonation performance of the two types of paints (exterior and interior paints) when applied to a reference concrete substrate. The test results showed a good linear relationship between the carbonation depths of the paint coated concrete and the square root of exposure times. Concrete with higher strength grade …
