US Egypt Cooperative Research:
Use of Cold-Formed Steel in Residential Housing

U.S. funding through US-AID adminitstered by National Science Foundation

 

Project Life: 2011-2014 

Summary

This project supported a cooperative research effort lead by Dr. Benjamin Schafer at Johns Hopkins University, Baltimore, Maryland and Dr. Metwally Abu-Hamd of Cairo University, Cairo, Egypt. The team studied the application of cold-formed steel framing to Egypt and also examined solutions that would allow a country newly adopting cold-formed steel building technology to leapfrog legacy solutions. In recent years society has begun to re-evaluate our built environment with the objective of achieving higher performance, specifically, to minimize loss attributed to natural hazards and to seek sustainable solutions for long-term needs in the built environment. Residential housing represents the greatest percentage of the world's building stock. In the past cultural norms largely drove the materials and systems employed for residential housing, today the situation is in flux and the potential to move towards a more scientific performance-basis exists. One material that may see significant increase in use due to its high strength-to-weight ratio, high recycled content, ease of construction, and proven efficiencies is cold-formed steel. The project explored the use of cold-formed steel framing in residential housing in Egypt and sought to (a) develop new non-proprietary systems for cold-formed steel framing with the potential to significantly increase building technical performance and function, and (b) provides a series of archetype studies that explore different framing solutions, including the newly proposed cold-formed steel option, from economic, environmental, and sustainability aspects. The building archetypes studies focus on both rural and urban areas in Egypt and the framing solutions examined include (a) traditional framing solutions in Egypt (concrete) along with (b) existing repetitive framing in cold-formed steel using commodity shapes and (c) novel, optimized, cross-section shapes and new systems for load bearing and lateral resistance.

Note: Prof. Metwally Abu-Hamd received additional Egyptian government funding in 2014 to continue the efforts and Prof. Schafer has continued the collaboration as a consultant. In December 2014 the team hosted a 2nd Egypt-U.S. workshop on the use of cold-formed steel in Egypt.

U.S. Industrial Advisory Board (IAB)

A key component of the project is the advice from the U.S. based Industrial Advisory Board. The project team met with advisory board in Fall 2011, and Spring 2012. In the Fall of 2012 several members of the IAB participated in a workshop held in Cairo. The members include

IAB Members:

Rick Haws - Nucor (Chair)

Don Allen - DSi Engineering, Super Stud

Jay Larson - Steel Market Development Institute (American Iron and Steel Institute)

Rob Madsen - Devco Engineeering

U.S. Meetings and Tours (April 2012)

The entire project team met in the U.S. in April of 2012.The meeting was planned in conjunction with the North American Steel Construction Conference held in Grapevine Texas. The team toured the cold-formed steel testing facilties at the University of North Texas lead by Associate Professor Cheng Yu. After attending the conference the entire group then went to Baltimore for additional tours and visit. A half-day day workshop covering all of the research in the JHU Thin-walled Structures group was provided along with a tour of the Thin-walled Structures laboratory and visits with administration and other faculty. The team toured a ClarkDietrich manufacturing facility and toured a load bearing cold-formed steel framed building using TSN studs in Wilmington. The team visited a cold-formed steel panelizer: Panel Systems in Woodbridge VA and toured a building using Panel Systems walls in downton Washington, D.C. The team finished its multi-say tour with a visit to the National Association of Home Builders Research Center in Upper Marlboro, MD. The tour, organized by the PI, provided a hands-on look at the application of cold-formed steel building technology in the United States. The project team would like to thank all those individuals who took time out of their busy schedules to host the team during their visits.

Egyptian Workshop (November 2012)
As Egypt Finds its Future, Engineers Gather to Envision Future Housing

Egypt is in political turmoil. Making a difference in these times is probably asking too much from a small joint USAID/NSF research project, but for two days in the second week of December 2012 approximately 200 Egyptian engineers, architects, builders, and manufacturers and even a few ministers from the Egyptian government met at the University of Cairo to imagine a future for Egypt that takes advantage of the latest technology: light (cold-formed) steel framing. The workshop was organized by Professor Metwally Abu-Hamd of the University of Cairo and Professor Benjamin Schafer of Johns Hopkins University as part of an ongoing grant that the two professors are leading: "US Egypt Cooperative Research: Use of Cold-Formed Steel in Residential Housing".

The workshop was led by the United States and Egyptian project teams and included key participation from the United States Industrial Advisory Board. Four members of that board: George Richards (BORM), Don Allen (DSi), Nader ElHajj (Framecad), and Nabil Rahman (TSN), came to Cairo to share their experiences with making light steel framing a reality not only in the United States, but around the world. Their talks were augmented by research talks from the project team (Egypt: Metwally Abu-Hamd, Maged Twafick Hanna, Mohammed Badr; United States: Benjamin Schafer, Zhanjie Li). An industrial exhibition also complemented the workshop and demonstrated to the Egyptian engineers that the manufacturing base was already in place to make light steel framing happen in Egypt.

Being in Egpyt, at the same time as protestors marched in Tahrir square, only made the Egyptian participants even more gracious with their United States participants. Benjamin Schafer summarizes: "It was a once in a lifetime chance to demonstrate that we care about an Egyptian future, without being political, instead we simply set down to the business of becoming better engineers and learning new skills so we can provide society with more from less."
