Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband 2017 California Polytechnic State University, San Luis Obispo

Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband

Architectural Engineering

Stochastic Subspace Identification is a field of applied mathematics that takes collected experimental time-history data and gives out information about the system that produced the data. SSI is typically used in control analysis but here we apply the methods to the modal analysis of structures. This senior project didn’t involve theory - instead much of the work was in research behind how Subspace Identification works, implementing the algorithm in MATLAB, and applying the program to shake table data to validate the program. In other words, building the framework to make SSI a usable tool and practical learning experience for other ...

The Ginkgo Shell, Mark Luzi, Karla Santos, Josh Cannon, Erika Davis, Nora Villanueva 2017 California Polytechnic State University, San Luis Obispo

The Ginkgo Shell, Mark Luzi, Karla Santos, Josh Cannon, Erika Davis, Nora Villanueva

Architectural Engineering

The overall concept for this outdoor concrete shell structure, located in Furstliche Park in Inzigkofen, Germany, is derived from an abstracted ginkgo leaf. Drawing on inspiration from a poem about the two parts of the ginkgo leaf becoming one, we took the approach of combining both the natural and built environment into one cohesive piece. To connect the two, it was imperative that we place the shell on the site as to have the smallest impact. With a small portion of the overall site used, the unoccupied space further enhances the natural environment. Creating a literal design connection between the ...


Mano De La Amistad: A Thin Shell Concrete Structure Designed For The People Of Havana, Cuba, Peter Aster, Marta Blachowicz-Scott, Aaron Cook, Alex Erler, Elizabeth Townsend, Ger Yang 2017 California Polytechnic State University, San Luis Obispo

Mano De La Amistad: A Thin Shell Concrete Structure Designed For The People Of Havana, Cuba, Peter Aster, Marta Blachowicz-Scott, Aaron Cook, Alex Erler, Elizabeth Townsend, Ger Yang

Architectural Engineering

In designing a thin shell structure to cover the performance space on Tribuna Anti Imperialista Jose Marti, in Havana, Cuba, we developed a heavily symbolic concept and further abstracted it to reach our design. Basing the concept on the quote to the right by Obama about US and Cuba relations, we wanted our design to be representative of a hand that works to adjoin the plaza to the US Embassy which is directly west of the site. The “wrist” portion adds an asymmetric element, while the fingers provide a backdrop to the performers as well as a view through to ...

Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson 2017 California Polytechnic State University, San Luis Obispo

Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

The first aspect of this project ...

Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach 2017 University of Nebraska-Lincoln

Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach

Lily M Wang

Previous studies have demonstrated the negative impact of adverse signal-to-noise-ratios on non-native English-speaking listeners' performance on speech recognition using recall tasks, as well as implied that comprehension skills were more impaired than recognition skills under reverberation and noise. The authors have themselves previously conducted a pilot study on three native and three non-native Englishspeaking listeners to examine the effects of reverberation and noise using speech comprehension tasks. Those results suggested that speech comprehension performance is worse under longer reverberation times (RT), and that a longer RT is more detrimental to speech comprehension by non-native listeners than native listeners. This paper ...


How Tonality And Loudness Of Noise Relate To Annoyance And Task Performance” Noise Control Eng. J. 65(2), 71-82., Joonhee Lee, Jennifer M. Francis, Lily M. Wang 2017 University of Nebraska - Lincoln

How Tonality And Loudness Of Noise Relate To Annoyance And Task Performance” Noise Control Eng. J. 65(2), 71-82., Joonhee Lee, Jennifer M. Francis, Lily M. Wang

Lily M Wang

Audible tones in noise generated by building mechanical equipment can be a leading cause of complaints from occupants. A number of metrics have been developed to quantify prominence of a tone, but previous work has shown that the impact of a certain tonality appears to vary with the level of the broadband noise signal. More work on how tonal signals of varying tonality, tone frequency and broadband noise levels relate to annoyance and task performance is needed. This paper investigates such relationships between current noise metrics, annoyance and task performance under assorted tonal noise conditions through subjective testing. Participants rated ...

Modular House Revival, Kevin Chiang, Spencer Dilley, Sarah Dowthwaite, Trevor Houghton, Ryan Lefebvre, Michele Leung, Cameron Lober, Chris Martinez, Katie Mayer

Architectural Engineering

The Modular House, located in Poly Canyon, has seen extensive damage since the last caretaker left nearly ten years ago. To prevent further damage and improve the safety and appeal of the structure, we are proposing a renovation of the existing building that removes the existing cladding and partitions. By the end of Spring Quarter 2017, the Modular House will have a guardrail system replacing the wood paneling on the walls and a new steel composite deck to replace the current flooring system. The structural steel framing system will remain as is.

Uncovering The Mystery Of Machu Picchu, Barbara Cardona 2017 Stanford University

Uncovering The Mystery Of Machu Picchu, Barbara Cardona

Butler Journal of Undergraduate Research

If mysteries were ranked, Machu Picchu would be on the top of the list. This Incan site, destination for millions of tourists, archaeologists and researchers each year, is one of the biggest enigmas of Incan culture. Its mesmerizing view has prompted hundreds of unanswered questions about this civilization. Incan culture revolved around cities, built without reference to the world beyond. Although the Incas were incredible architects and inventors, they lack written records, shrouding their culture in mystery for many years. While research has illuminated some facets of Incan culture, a significant question still remains: what purpose did Machu Picchu play ...


Experimental And Numerical Investigation Of Flexural Concrete Wall Design Details, Anahid A. Behrouzi, T. Welt, Dawn Lehman, Laura Lowes, J. LaFave, Daniel Kuchma 2017 California Polytechnic State University, San Luis Obispo

Experimental And Numerical Investigation Of Flexural Concrete Wall Design Details, Anahid A. Behrouzi, T. Welt, Dawn Lehman, Laura Lowes, J. Lafave, Daniel Kuchma

Architectural Engineering

Reinforced concrete structural walls are common in mid- to high-rise structures in high seismic regions, and are expected to have good strength and ductility characteristics if designed in accordance with ACI 318-14. However, experimental and analytical investigations of reinforced concrete structural walls and isolated boundary element prisms indicate that the existing design provisions may be insufficient to provide ductile, flexure-dominated response under cyclic loading. Walls designed with an ACI compliant boundary element length are susceptible to shear-compression failures below the maximum ACI allowable shear stress of 10Acv√fc’. Also of concern is the frequent use of thinner walls in modern ...
