A Comparative Study Of The Physical Elements In Shiraz Traditional Districts With The Features Of Cpted Approach, Mohammadreza Mohseni, Ahoura Zandiatashbar, Mohammad Masud
Faculty Publications, Urban and Regional Planning
Neighborhood space and district is an issue that has been forgotten in contemporary architecture of cities. With regard to the quantitative increase of districts and also the increase of a unilateral physical view towards them, their security declines and consequently the capacity for crime increases in the residential spaces and fear of crime occurrence among the residents of the districts. In the environmental design, the CPTED attitude is one of the most effective approaches to enhance security. The main pivot of this article is to study the rate of agreements of the physical elements of old districts of Shiraz with …

Plants As Bio-Indicators Of Subsurface Conditions: Impact Of Groundwater Level On Btex Concentrations In Trees, Jordan Wilson, Rachel Bartz, Matt Limmer, Joel Gerard Burken
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Numerous Studies Have Demonstrated Trees' Ability to Extract and Translocate Moderately Hydrophobic Contaminants, and Sampling Trees for Compounds Such as BTEX Can Help Delineate Plumes in the Field. However, When BTEX is Detected in the Groundwater, Detection in Nearby Trees is Not as Reliable an Indicator of Subsurface Contamination as Other Compounds Such as Chlorinated Solvents. Aerobic Rhizospheric and Bulk Soil Degradation is a Potential Explanation for the Observed Variability of BTEX in Trees as Compared to Groundwater Concentrations. the Goal of This Study Was to Determine the Effect of Groundwater Level on BTEX Concentrations in Tree Tissue. the Central …

Appropriate Viscous Damping For Nonlinear Time-History Analysis Of Base-Isolated Reinforced Concrete Buildings, Deepak R. Pant, Anil C. Wijeyewickrema, Mohamed A. Elgawady
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
SUMMARY: There is no consensus at the present time regarding an appropriate approach to model viscous damping in nonlinear time-history analysis of base-isolated buildings because of uncertainties associated with quantification of energy dissipation. Therefore, in this study, the effects of modeling viscous damping on the response of base-isolated reinforced concrete buildings subjected to earthquake ground motions are investigated. The test results of a reduced-scale three-story building previously tested on a shaking table are compared with three-dimensional finite element simulation results. The study is primarily focused on nonlinear direct-integration time-history analysis, where many different approaches of modeling viscous damping, developed within …

Awareness At A Threshold: Urban Exchange Through Public Space, Matthew Spears
Architecture Theses and Projects
The moment of arrival becomes an important opportunity for cultural exchange in an urban environment. This exchange can be both the physical exchange between two places or it can be the experiential exchange between two or more disparate groups. These moments of exchange are an elusive experience for visitors as well as residents and are easily forgotten. Expressing the space of the traveler, an interactive space between locals and visitors, can raise cultural awareness between the most prominent groups as well as the marginalized groups, creating a more cohesive urban imaginary. The major exchange hub in Seattle, Washington speaks to …

Cohousing And The Greater Community: Re-Establishing Identity In Taunton’S Weir Village, Andrew Kremzier
Architecture Theses and Projects
This proposal seeks to bring new life to the former industrial district of the post-industrial city. Existing in a society based on services and technologies, these villages must either adapt to meet the needs of business or serve another purpose within the community. The project for the Weir Village falls into the latter category, as its aim will be to create a cohousing community within Taunton. The new development will strengthen the character of the village and be able to affect the community beyond the site’s physical boundaries. It will create affordable alternatives to housing for those who do not …

Humility And Homelessness: A Housing Continuum, Jessica Macdonald
Architecture Theses and Projects
The design of a housing continuum in Burlington provides a variety of support environments. These different housing environments are all designed within the downtown area, providing access to public transportation, open part space and employment opportunities. Support services play a huge role in an individual’s process to self-sufficiency. Many social services are already located in the downtown area, however the relationship between living space and support space is important. This thesis introduces three housing typologies as architectural interventions on three under-utilized downtown sites, focusing on the relationship between the individual and the common.

Using Architecture Pedagogy To Enhance Engineering Education, Shannon Chance, Mike Murphy, Gavin Duffy, Brian Bowe
Conference papers
Based on evidence, numerous advisory boards and scholars insist engineering education must change (NSB, 2007; McKenna, Froyd, King, Litzinger, & Seymour, 2011) and that hands-on, inquiry-driven, project-based learning pedagogies can enhance STEM education (Boyer & Mitgang, 1996). These pedagogies have formed the core of architectural education since the Renaissance and have been in continuous use since that time. As such, engineering educators can benefit from observing how architecture students learn and understanding how they are taught. Likewise, architecture can benefit from applying the group-based learning strategies employed by engineering teachers who use studentcentered, project-based pedagogies. Trans-disciplinary approaches hold particular merit.

Some Insights For The Prediction Of Near-Wall Turbulence, Farid Karimpour, Subhas K. Venayagamoorthy
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
In this paper, we revisit the eddy viscosity formulation to highlight a number of important issues that have direct implications for the prediction of near-wall turbulence. For steady wall-bounded turbulent flows, we make the equilibrium assumption between rates of production (P) and dissipation (ε) of turbulent kinetic energy (κ) in the near-wall region to propose that the eddy viscosity should be given by vt ε/S2, where S is the mean shear rate. We then argue that the appropriate velocity scale is given by (STL)-1/2 k1/2 where TL = k ε is the turbulence (decay) time scale. The …

Scale Of Fluctuation Of Geotechnical Parameters Estimated From Cptu And Laboratory Test Data, Site Onyejekwe, Louis Ge
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
For a complete probabilistic characterization of a geotechnical parameter, its mean, variance, and the scale of fluctuation have to be known. While the mean and variance can be easily determined, determination of the scale of fluctuation is a little more complex. Knowledge of the scale of fluctuation is important in reliability-based design as it is used in implementing spatial averaging and computing the variance-reduction factor. Published values of scale of fluctuation of geotechnical parameters are based on widely sourced data and hence may not be most appropriate for local situations. Based on 11 CPTu soundings and laboratory test results of …
Probability Of Failure For Slopes With Sensitivity Analysis,

Probability Of Failure For Slopes With Sensitivity Analysis, Michelle Deng, Ronaldo Luna
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
The significance of random variables on the probability of failure of slopes is generally evaluated by changing a different set of values for each variable and repeating the approach several times to conclude a trend. This method is very straightforward but requires time and computational resources; and it is inefficient especially when the number of random variables is large. This paper presents an analysis approach in which the sensitivity analysis is introduced to quantify the influence of the random variables on the probability of failure for slopes. In this study, the factor of safety of the slope was determined using …

This paper presents a seismic design procedure for self-centering precast post-tensioned bridge piers. The piers presented in this manuscript consisted of concrete filled fiber reinforced polymer (FRP) tubes. A large set of 84 piers with different design parameters were analyzed using finite element models. The backbone curve of each pier was developed and bilinearized. The idealized backbone curves were used to develop a set of empirical equations that were able to reproduce the bilinearized backbone curve of a given pier. Different performance criteria have been proposed for the system according to the intensity and the frequency of occurrence of a …

The process used to calculate and reduce the consequences of meteoroid and orbital debris (MOD) penetrations and their link to catastrophic failure has evolved over time. As the threat of the orbital debris population increased in the 1980s and early 1990s, NASA developed a tool to determine the probability of no catastrophic failure, or PNCF, for the space station and to assess possible changes in station design and/or operations to improve that survivability percentage. PNCF is directly related to the PNP, or probability of no penetration, as calculated by Bumper, the code used by NASA to perform MOD risk assessments. …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Every year concrete production exceeds 6.5 billion tons worldwide, nearly 1 ton for every man, woman, and child on the planet. In fact, concrete is used 10 times more than any other building material in the world, primarily because of its incredible versatility, availability, and relatively low cost. Unfortunately, the production of Portland cement - the key ingredient in concrete - generates approximately a pound of carbon dioxide for every pound of cement produced. One method of reducing concrete's carbon footprint is to replace a significant amount of the cement with fly ash, a by-product of coal-burning thermal power stations. …
