Capstone Projects: Integrating Industry Through Student Leadership, Brent Nuttall, James Mwangi, Craig Baltimore

Architectural Engineering

Capstone projects provide a unique opportunity for developing student leadership skills while integrating industry partners. While models for including industry partners in capstone projects have been discussed in prior literature, these models focus on faculty leadership in developing industry partnerships. This paper describes a capstone project model that encourages student, not faculty, leadership in engaging industry partners. Factors that influence successful project teaming of students and industry partners are identified and described using case study examples. The successes and difficulties of integrating industry in capstone project via student leadership are explored.

Teaching The Design: Timber Shear Walls And Developing Student Engineering Judgement And Intuition Through A Hands-On Experience, Craig Baltimore, James Mwangi, Brent Nuttall

Architectural Engineering

Engineering judgement and intuition are vital characteristic of the design profession. Engineering judgement and intuition are developed through experience. This experience is gained by designing a building (working with industry disciplines and the owner); analyzing the building (calculations); being part of the construction process (constructability), and walking through the final product (end user). Teaching design means, in part, developing engineering judgement and intuition. This may best be accomplished by incorporating active learning experiences.

For timber and masonry buildings, the shear wall is the lateral resisting system of choice. A hands-on experience has been developed as a simple exercise in constructing …

Corporate Social Responsibility Of Architectural Design Firms Towards Sustainable Built Environment In South Africa, Ayman Ahmed Ezzat Othman

Architectural Engineering

The construction industry makes a vital contribution to the social and economic development of every country. Buildings provide their users with places for housing, education, culture, medication, business, leisure and entertainment. None of these buildings will perform its function unless supported with efficient road networks, superlative telecommunications facilities, water and electricity. On the other hand, the construction industry has major impacts on the environment. It is a very large consumer of non-renewable resources, a substantial source of waste, pollution, land dereliction and energy consumption. This highlights the responsibility of present generations to use the available resources in a way that …

Incorporating Constructability In The Design Of Masonry Structures, James Mwangi, Craig Baltimore

Architectural Engineering

The International Building Code (IBC) has now been adopted as the model design code for most states and territories of the United States of America. For Masonry design, the IBC references the Building Code Requirements and Specification for Masonry Structures (MSJC) for material properties, design procedures, specifications and quality control. Individual state codes then amend the two documents (IBC and MSJC) appropriately.

In high seismic regions of the United States, hollow block of concrete masonry units (CMU) are the material of choice in masonry construction. The CMU’s are built using sand, pea gravel, cement and water. CMU is typically delivered …

Researchers And Practitioners: A Dual Track Path To Tenure That Works, Allen Estes, Brent Nuttall, Cole C. Mcdaniel

Architectural Engineering

The American Society of Civil Engineers (ASCE) has published the Civil Engineering Body of Knowledge (BOK) for the 21st Century and has produced a draft version of the follow-on BOK II, both which attempt to define the knowledge, skills and attitudes required of a civil engineer. A section of that document addresses who should teach this body of knowledge. It concludes that civil engineering faculty must be scholars, effective teachers, practitioners, and role models. In most universities, practitioners are included on the faculty as adjunct professors. They are paid less and are not viewed as full-fledged partners. The Architectural Engineering …

Simplicity, Scale, And Surprise: Evaluating Structural Form, Edmond P. Saliklis, Michael Bauer, David P. Billington

Architectural Engineering

Aesthetic and ethical issues of building design are presented here to encourage meaningful discussion among today’s architectural engineering students and practitioners. The evaluative aesthetic ideas of scale, simplicity, and surprise are applied to two important structures designed by Fazlur R. Khan. Khan’s profound understanding of load flow in his buildings influenced his aesthetic ideas. Furthermore, his aesthetic ideas were intimately intertwined with his ethical ideas about structural logic and the role of structure in architecture. We explore these ideas and present new insights as well. Our goal is to encourage a public discourse within our profession on the topic of …

Tilt-Up Building Seismic Design - Precast Or Cast-In Place?, Joe Steinbicker, John Lawson

Architectural Engineering

Tilt-up buildings have been successfully designed and constructed throughout the United States for over fifty years. Today, the tiltup method of construction is used extensively to build all types of buildings, currently at a rate of 300,000,000 square feet of tilt-up concrete panels constructed in the United States each year. Recently, with the adoption of the 2006 edition of the International Building Code (IBC) in conjunction with the ASCE 7-05 Minimum Design Loads for Buildings and Other Structures , there has developed some confusion over what building type should tilt-up construction be classified for the purposes of seismic design – …

Thinking Outside The Box: New Approaches To Very Large Flexible Diaphragms, John W. Lawson

Architectural Engineering

This paper discusses the past design practices of flexible diaphragms, the current trend to very large diaphragms, and the new tools available to properly evaluate and engineer these large roof systems. Higher shear demands are accommodated by higher plywood/OSB and steel deck shear capacities accepted by the IBe. A new collective chord technique is presented to more accurately reflect large diaphragm behavior. In addition, these very large diaphragms have significant lateral deflection issues that can now be evaluated in the IBC. The new AF&PA deflection equations for wood diaphragms are presented as well as a technique to compute deflections of …

Deflection Limits For Tilt-Up Wall Serviceability - The History Behind Changes To Chapter 14 Of Aci 318, John Lawson

Architectural Engineering

Tilt-up construction is one of the most ubiquitous forms of commercial construction in many parts of the country. Thanks to its efficient wall and roof systems, more than 700 million ft² (65 million m²) of tilt-up buildings were constructed in the U.S. in 2006.¹
Tilt-up's current popularity is even more remarkable considering that it wasn't until the 1980s that building codes began to recognize the unique design of slender tilt-up wall panels. In fact, it wasn't until ACI 318-99² was published that the design of slender wall panels was codified on a national level. Of …

Two Alternative System Reliability Approaches To The Serviceability Condition Assessment Of Spillway Gate Systems On Dams, Allen C. Estes, Stuart D. Foltz

Architectural Engineering

Two competing methods were introduced for analyzing the condition of a structural system. The results produced by both were very different. In the weighted average approach, the system condition index will always be somewhere between the condition of the best and worst component in the system. In the traditional reliability approach, the condition index will always be lower than the condition of the worst member in a series system and higher than the condition of the best member in a parallel system. A traditional reliability approach works extremely well for a strength-based system where the importance factors of the components …

Ubc 97 And Aci 318-02 Code Comparison - Summary Report, Chukwuma Ekwueme, John Lawson, Mehran Pourzanjani, James S. Lai, Bob Lyon

Load Rating Versus Reliability Analysis, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

The most common approach to assess the safety of a bridge is load rating. However, this approach cannot quantify the bridge safety in probabilistic terms or fully quantify the structural risk to the bridge. Reliability methods have become an increasingly popular and gradually accepted approach to assess the safety of structures. These methods account for the randomness and correlation of all relevant variables and failure modes in the analysis. This study performs both a load rating analysis and a reliability analysis on the same highway bridge, compares the results, and discusses the strengths and limitations of each approach.

Bridge Deck Replacement For Minimum Expected Cost Under Multiple Reliability Constraints, Mark G. Stewart, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

The present paper investigates the effect of limit state selection (strength versus serviceability) on bridge deck life-cycle costs and thus on optimal repair strategies. Such a comparison may then help determine whether safety or functionality (or both) are important criteria when optimizing bridge life-cycle performance and costs. The structural element under consideration is a reinforced concrete bridge deck; namely, a State Highway Bridge in Colorado. Two limit states are considered: ultimate strength and serviceability. The exceedence of either of the limit states considered herein will result in deck replacement; namely, if the reliability index falls below a target reliability index …

Updating Reliability Of Steel Miter Gates On Locks And Dams Using Visual Inspection Results, Allen C. Estes, Dan M. Frangopol, Stuart D. Foltz

Architectural Engineering

As both reliability analyses and systematic inspection programs for the world’s infrastructure gain increased usage and prominence, it becomes more important to use the information from routine visual inspections to update lifetime reliability assessments and resulting life-cycle inspection/repair strategies. The Army Corps of Engineers currently uses reliability analyses to economically justify the major rehabilitation of navigation structures. This paper illustrates how the Condition Index visual inspections for locks and dams can be modified and used to update the reliability analysis of a steel miter gate. The miter gates on two existing locks and dams along the Mississippi River are used …

Updating Bridge Reliability Based On Bridge Management Systems Visual Inspection Results, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

Bridge management systems have become increasingly sophisticated over the past decade and provide valuable information about the structural condition of all bridges in the national database. At the same time, reliability methods have gained increasing prominence and are used to forecast life-cycle performance over many decades of structural life. Such reliability analyses need to be updated based on the results of inspections. Specifically targeted nondestructive evaluations are the preferred solution, but are not always available for every bridge. This paper examines how the visual inspection data provided from bridge management systems already in place can be used to update the …
