Verifying The Cause Of Panel Cracking - A Case Study, Jack Robinson, Stewart Hooks, John W. Lawson

Architectural Engineering

Despite the multitude of benefits tilt-up construction has to offer in low rise commercial buildings, there is still room for improvements in the performance of tilt-up buildings. One opportunity for improvement is to minimize a particular, undesirable cracking pattern often seen in concrete tilt-up panels (See Figure 1), which in some cases requires significant cosmetic patching (See Figure 2). This concrete cracking can first appear as non-problematic and non-structural, but even small cracks can become weathered and lead to water intrusion and rebar corrosion. At the very least, these cracks are cosmetic concerns for the owner or tenant potentially resulting …

Holistic Interdisciplinary Design - Everyone Does Everything (Engineering Students As Sculptors), Craig Baltimore, Allen C. Estes

Architectural Engineering

The ability to offer students an interdisciplinary experience under a team work setting is invaluable in preparation for a career in the built environment. A hands-on approach coupled with a real project presents unique opportunities in student learning. Learning in regards to the dynamics of team personalities, deadlines, approval procedures, and deliverables. One such hands-on based real project was to design, build, and install an 800 lb., 20 ft. long, and 10 ft. tall sculpture. The sculpture was to be built of recycled steel of a mustang in 10 weeks for the University’s library Spring 2016 exhibit. The project gave …

Developing A Robust Teaching Portfolio As A Doctoral Student In A Research-Intensive Engineering Program, Anahid A. Behrouzi

Architectural Engineering

Successful faculty applications to teaching/undergraduate institutions can be difficult for doctoral students transitioning directly from a research-intensive engineering program. Oftentimes, these prospective faculty members have limited opportunities to engage in engineering education research, to serve as a primary instructor for a lecture course, or to receive adequate mentoring to prepare them for the environment of a teaching/undergraduate institution.

This paper will highlight the lessons learned by a new faculty member at a top-ranked undergraduate institution (and recent doctoral candidate at a R1 research institution) about how students can build a comprehensive teaching portfolio outside of the traditional coursework and research …

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 …

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 …

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 …

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 …

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.

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 design; …

Evaluation Of Out-Of-Plane Wall Anchorage Force Provisions In Buildings With Rigid Walls And Flexible Roof Diaphragms, Maria Koliou, John W. Lawson, Andre Filiatrault, Dominic J. Kelly

Architectural Engineering

Heavy concrete and masonry walled buildings with lightweight steel or wood flexible roof diaphragms are a common type of construction in North America. Failures of the out-of-plane wall anchorage to these roof systems and the resulting partial roof collapses during past earthquakes have led to repeated revisions to the seismic design provisions in the U.S. model building codes. However, the force levels considered in the current design provisions have remained largely unchanged since their introduction in the 1997 Uniform Building Code, and these provisions have not been fully tested by strong ground motions in the field. Using a two dimensional …

Roof Diaphragm Distributed Yielding Concept For Improved Seismic Collapse Performance Of Buildings With Rigid Walls/Flexible Roof Diaphragms, Maria Koliou, Andre Filiatrault, D.J. Kelly, John W. Lawson

Architectural Engineering

Buildings with rigid walls and flexible roof diaphragms (RWFD) are a common type of single-story construction in North America, Europe and New Zealand that incorporate rigid in-plane concrete or masonry walls and flexible in-plane wood or steel roof diaphragms. RWFD buildings have shown poor seismic performance during past earthquake events. In particular, it has been observed that the global seismic response is dominated by the response of the roof diaphragm, which is mainly attributed to large in-plane roof displacements that significantly exceed the displacements of in-plane walls. The present study explores the concept of distributed yielding in the flexible roof …

An Alternative Procedure For The Seismic Design Of Buildings With Rigid Walls / Flexible Diaphragms: Fema P-1026, John W. Lawson, Dominic J. Kelly, Maria Koliou, Andre Filiatrault

Architectural Engineering

Evidence indicates that the dynamic behavior of Rigid Wall - Flexible Diaphragm (RWFD) buildings is dominated by the flexible roof diaphragm’s response instead of the walls’ response, and this is a significant departure from the underlying assumptions of the widely used equivalent lateral static force methods in current building codes. RWFD buildings are common in the Americas and other parts of the world, and incorporate rigid in-plane concrete or masonry walls and flexible in-plane wood or steel roof diaphragms. In an effort to improve the seismic performance of this common building type, the National Institute of Building Sciences (NIBS) directed …

Impact Of Cross Section, Web Reinforcement And Load History On The Seismic Performance Of Slender Concrete Walls, Anahid A. Behrouzi

Architectural Engineering

Many reinforced concrete buildings in seismic regions employ reinforced concrete shear walls as part of the lateral force resisting system and these walls often have non-planar cross-sectional geometries. To date, the majority of experimental tests on slender concrete walls have been conducted on planar walls which have been subject to low shear stress demands. An experimental program was developed to examine the response of flanged C-shaped walls with respect of load history and a computational parametric study was conducted to focus more specifically on the impact of web reinforcement for walls subject to a range of shear stress demands.

The Making Of A Rain-Induced Roof Collapse And The Lessons Learned For Our Profession, M. E. Parolini, John Lawson

Architectural Engineering

Using a recent rain-induced roof collapse as a forensic case study, the authors will demonstrate a number of vital points of interest in the collaboration between structural engineers and other design disciplines. Citing a number of problems with the building’s design and the current code standards, this paper will investigate the avoidable events that led to a costly failure of the roof structure presented. As the practice of each construction design profession has become more specialized, communication among those professions on many overlapping design choices has eroded from common practice. This is true for one such area where multiple disciplines …

Accreditation Insights And The Next Body Of Knowledge, Allen Estes, Thomas A. Lenox, Kenneth J. Fridley, Richard O. Anderson P.E.

Architectural Engineering

The American Society of Civil Engineers (ASCE) published the second edition of the Civil Engineering Body of Knowledge (BOK2) in 2008 expanding the knowledge, skills and attitudes required of future civil engineers. There were major changes to the BOK2 as the number of expected outcomes increased from 15 to 24 and the cognitive level of attainment was more precisely defined. A major implementation and enforcement mechanism for the BOK is the ABET accreditation criteria which includes both general criteria 3 and 5 and the discipline-specific program criteria. Of those, the program criteria are the easiest to change.

In 2013, ASCE …
