Aspen Art Museum, Rumiko Handa

Architecture Program: Faculty Scholarly and Creative Activity

'I hope when people come to the New Aspen Art Museum they will sense that this building is very much at home in Aspen and could only live here', Shigeru Ban states in a short essay to visitors included in the museum brochure. Indeed, the way in which Ban's design fits uniquely within its context is nothing less than extraordinary. A full appreciation of his accomplishment, however, requires a study of Aspen's history.

What strategies are available to the architect who intends to design a museum that fits well for a community with keen interests in arts but lacking in …

Failure At Fidenae: Visualization And Analysis Of The Largest Structural Disaster In The Roman World, Rebecca Napolitano

Physics, Astronomy and Geophysics Honors Papers

A digital reconstruction of the amphitheater at Fidenae, which collapsed in 27 A.D., was produced as a result of textual, architectural, archaeological, and engineering analysis. Primary literary sources, such as Tacitus and Suetonius, examined in conjunction with proximal archaeological evidence, allowed for the most probable seating capacity and the scale of the amphitheater to be determined. Architectural evidence of other wooden structures found on Trajan’s Column allowed for a most probable projection of a three dimensional model to be created using AutoCAD. With this most probable model determined, engineering analysis was utilized in order to understand the failure at Fidenae …

Influence Of Collaborative Learning On Women’S Experiences Of Engineering Education, Shannon Chance, Brian Bowe

Other resources

In a study of 55 electrical engineering students, Yadav, et al., found learning gains among students in Project-Based Learning (PBL) to be twice the gains of those taking traditional lecture courses. Du and Kolmos indicate groupbased PBL is more supportive and appealing to women than traditional lecture formats. Savin-Baden posits that female and minority students are more likely to ask questions in non-competitive PBL environments. This study interrogates the claim that PBL is particularly supportive to female and minority students. This work-in-progress uses a phenomenological research methodology to investigate how collaborative learning (in formal as well as non-formal settings) influences …

Architectural Acoustical Oddities, Zev C. Woodstock, Caroline P. Lubert

Department of Mathematics and Statistics - Faculty Scholarship

This paper offers a review of two types of acoustic oddity caused by periodic architecture. These periodic structures of interest are brick plazas and staircases with special dimensions. When an observer stands by one of these periodic structures and produces a percussive white noise, a high-pitched sound can be heard. The frequency of the returned sound is unrelated to the initial sound, and completely determined by the architecture of the structures themselves. This phenomenon is called repetition pitch. Comparative work done at James Madison University is offered to show the relationship between brick plazas at JMU and the repetition pitch …

Air Change Rate Vs Airflow Pathway: Bioaerosol Containment And Removal In Patient Rooms, Kevin R. Grosskopf

Durham School of Architectural Engineering and Construction: Faculty Publications

Recent studies have shown that higher air change rates may have the unintended consequence of creating turbulent airflows that entrain high concentrations of infectious particles within the breathing zone, and possibly, breakdown pressure relationships necessary to contain the spread of infectious particles to other clinical spaces.

Use Of Fiber-Reinforced Cements In Masonry Construction And Structural Rehabilitation, Ece Erdogmus

Durham School of Architectural Engineering and Construction: Faculty Publications

The use of fiber reinforcement in traditional concrete mixes has been extensively studied and has been slowly finding its regular use in practice. In contrast, opportunities for the use of fibers in masonry applications and structural rehabilitation projects (masonry and concrete structures) have not been as deeply investigated, where the base matrix may be a weaker cementitious mixture. This paper will summarize the findings of the author’s research over the past 10 years in these particular applications of fiber reinforced cements (FRC). For masonry, considering both mortar and mortar-unit bond characteristics, a 0.5% volume fraction of micro fibers in type …

Vibration Of Steel-Framed Floors Supporting Sensitive Equipment In Hospitals, Research Facilities, And Manufacturing Facilities, Di Liu

Theses and Dissertations--Civil Engineering

Floors have traditionally been designed only for strength and deflection serviceability. As technological advances have been made in medical, scientific and micro-electronics manufacturing, many types of equipment have become sensitive to vibration of the supporting floor. Thus, vibration serviceability has become a routinely evaluated limit state for floors supporting sensitive equipment. Equipment vibration tolerance limits are sometimes expressed as waveform peak acceleration, and are more often expressed as narrowband spectral acceleration, or one-third octave spectral velocity.

Current floor vibration prediction methods, such as those found in the American Institute of Steel Construction Design Guide 11, Floor Vibrations Due to Human …

Ventilation Rates And Airflow Pathways In Patient Rooms: A Case Study Of Bioaerosol Containment And Removal, Ehsan S. Mousavi, Kevin R. Grosskopf

Durham School of Architectural Engineering and Construction: Faculty Publications

Most studies on the transmission of infectious airborne disease have focused on patient room air changes per hour (ACH) and how ACH provides pathogen dilution and removal. The logical but mostly unproven premise is that greater air change rates reduce the concentration of infectious particles and thus, the probability of airborne disease transmission. Recently, a growing body of research suggests pathways between pathogenic source (patient) and control (exhaust) may be the dominant environmental factor. While increases in airborne disease transmission have been associated with ventilation rates below 2 ACH, comparatively less data are available to quantify the benefits of higher …

An Adaptive Photovoltaic Topology To Overcome Shading Effect In Pv Systems, Mohamed Amer Chaaban, Lana El Chaar, Mahmoud Alahmad

Durham School of Architectural Engineering and Construction: Faculty Publications

Shading in photovoltaic systems can cause many undesired effects.When shading occurs, the power generated from the PV system is much less than nominal power, increasing the electrical mismatching losses between PV system components. Active research to address this power loss focuses on static and adaptive systems.This paper addresses an adaptive system solution and proposes a new method to adaptively overcome losses due to shading during low radiation conditions. In addition, a statistical analysis for choosing the most feasible and efficient configuration for the system size is presented. The proposed system has been validated under shade conditions in a simulation and …

A Review Of Approaches For Sensing, Understanding, And Improving Occupancy-Related Energy-Use Behaviors In Commercial Buildings, Hamed Nabizadeh Rafsanjani, Changbum R. Ahn, Mahmoud Alahmad

Durham School of Architectural Engineering and Construction: Faculty Publications

Buildings currently account for 30–40 percent of total global energy consumption. In particular, commercial buildings are responsible for about 12 percent of global energy use and 21 percent of the United States’ energy use, and the energy demand of this sector continues to grow faster than other sectors. This increasing rate therefore raises a critical concern about improving the energy performance of commercial buildings. Recently, researchers have investigated ways in which understanding and improving occupants’ energy-consuming behaviors could function as a cost-effective approach to decreasing commercial buildings’ energy demands. The objective of this paper is to present a detailed, up-to-date …

Development Of Composite Pcms By Incorporation Of Paraffin Into Various Building Materials, Shazim Ali Memon, Wenyu Liao, Shuqing Yang, Hongzhi Cui, Syed Farasat Ali Shah

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this research, we focused on the development of composite phase-change materials (CPCMs) by incorporation of a paraffin through vacuum impregnation in widely used building materials (Kaolin and ground granulated blast-furnace slag (GGBS)). The composite PCMs were characterized using environmental scanning electron microscopy (ESEM), Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) techniques. Moreover, thermal performance of cement paste composite PCM panels was evaluated using a self-designed heating system. Test results showed that the maximum percentage of paraffin retained by Kaolin and GGBS was found to be 18% and 9%, respectively. FT-IR results show that …

A Shear-Based Parameterization Of Turbulent Mixing In The Stable Atmospheric Boundary Layer, Jordan M. Wilson, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, shear-based parameterizations of turbulent mixing in the stable atmospheric boundary layer (SABL) are proposed. A relevant length-scale estimate for the mixing length LM of the turbulent momentum field is constructed from the turbulent kinetic energy Ek and the mean shear rate S as. Using observational data from two field campaigns-the Surface Heat Budget of the Arctic Ocean (SHEBA) experiment and the 1999 Cooperative Atmosphere-Surface Exchange Study (CASES-99)- is shown to have a strong correlation with LM. The relationship between LM and corresponds to the ratio of the magnitude of the tangential components of the turbulent momentum flux …

Hydraulic Design Of Baffles In Disinfection Contact Tanks, Zachary H. Taylor, Jeremy S. Carlston, Subhas Karan Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study focuses on understanding the hydraulic design of baffled contact tanks using computational fluid dynamics simulations. In particular, we address the key question: for a given footprint of a rectangular tank with a specified inlet width (Winlet), how does the hydraulic efficiency of a baffled tank depend on the configuration of internal baffles? In an effort to address this question, a carefully conceived parametric study consisting of 30 high-resolution two-dimensional (planar) simulations was conducted to quantify the hydraulic efficiency of a laboratory scale tank as a function of dimensional relationships between key baffle design dimensions (baffle opening length Lbo, …
