Top StoriesRevised AISI Prescriptive Method Approved as American National StandardThe revised AISI Standard for Cold-Formed Steel FramingPrescriptive Method for One and Two Family Dwellings has just been approved as an American National Standard by the American National Standards Institute (ANSI). In response to the need for increased performance by building materials in hostile weather conditions, AISI's revised Prescriptive Method has increased the wind load requirement for residential framing up to 150 mph. This change has made steel more competitive in high-wind regions such as south Florida and the U.S. Gulf Coast. When the AISI Standard for Cold-Formed Steel FramingPrescriptive Method for One and Two Family Dwellings was first developed, it was decided to limit the provisions to 130 mph exposure C wind. This excluded use of the Prescriptive Method from portions of south Florida and the Gulf Coast region, and was a judgment call based on perceived market needs. It was not felt that there would be a high demand for prescriptive provisions in higher-challenge areas. Since that decision, an International Code Council (ICC) Committee on Hurricane Resistant Construction was formed and work began on a Standard for Residential Construction in High Wind Regions. This committee desired that prescriptive provisions be established for areas up to 150 mph exposure C wind. A portion of the coastal region affected by Hurricanes Katrina and Rita is classified as 140 or 150 mph exposure C wind, as is a portion of south Florida. With funding support from the Steel Framing Alliance and the supervision of Jay Larson, AISI director of Construction Standards Development, a project was initiated in February 2006 with the National Association of Home Builders (NAHB) Research Center to perform the necessary analysis and develop the substantiation for changes, which were then balloted through the AISI Committee on Framing Standards. A public review of the final document was accomplished in accordance with ANSI procedures and the revised Prescriptive Method was approved as an American National Standard on September 8, 2006. The standard will now be more useful in the regions affected by Hurricanes Katrina and Rita. It will be published on September 27, 2007 and available for purchase at the Steel Framing Alliance online store at www.steelframing.org. Through the efforts of Robert Wills, AISI director of Construction Codes and Standards, it is also expected that the standard will be adopted by reference in the new ICC Standard for Residential Construction in High Wind Regions, which should provide a means for its adoption in south Florida and the Gulf Coast region.

AISI Joins Others for National Vehicle Mercury Switch Recovery ProgramIn August, AISI joined forces with the Environmental Protection Agency (EPA), the Alliance of Automobile Manufacturers, the Steel Manufacturers Association, the Institute of Scrap Recycling Industries, the Automotive Recyclers Association, Environmental Defense, the Ecology Center (Ann Arbor), and representatives of the Environmental Council of the States in an agreement known as the National Vehicle Mercury Switch Recovery Program. The program is the result of a two-year collaborative effort among these environmental and industry organizations to find a solution to the mercury switch issue. The program is aimed at removing mercury switches found in vehicles manufactured prior to 2003 before they become part of the auto-scrap recycling infrastructure. Since mercury is a toxic element to the environment, having these switches removed is an important step in making the auto-scrap recycling infrastructure more environmentally sound. "The automobile is America's most recycled consumer good containing America's most recycled materialsteel," said Andrew G. Sharkey, III, president and CEO of AISI. "It is imperative that we protect the scrap infrastructure from contaminants." The steel industry believes that the best way to reduce the amount of mercury contaminants in the scrap stream is to remove the mercury containing components before the scrapped automobile reaches the scrap stream. This program is a considerable step towards achieving that objective. "This process will significantly reduce mercury in steel scrap, which is a feedstock for steelmaking. At the same time, it will render significant benefits to the environment," said David Sutherland, president and CEO of IPSCO, Inc. and a member of AISI's Board of Directors. "We are committed to working with our partners and with EPA to reach the mercury reduction goals that are laid out in this agreement." The steel industry has committed $2.0 million in funding for the program. All AISI member companies with melting capacity will be asked to sign on to the program and help finance the fund. In addition, thousands of mercury switch removal buckets have been sent out to auto dismantlers around the country. These buckets include pertinent information about the program and how the removal process works. This program will truly be a collaborative effort on the parts of AISI member companies, scrap processors, auto dismantlers and the other environmental and industry organizations that have agreed to be a part of this program.

Robinson. MOE: Environmentally Friendly Alternative for Iron MakingAISI announced this August that under the leadership of Professor Donald R. Sadoway, in the Department of Materials Science Engineering, a team at the Massachusetts Institute of Technology (MIT) has successfully demonstrated the technical viability of producing iron by molten oxide electrolysis (MOE) in a laboratory scale-cell. As part of the AISI/Department of Energy (DOE) Technology Roadmap Program (TRP), producing iron in the lab by MOE represents a significant stride and is a positive signal about the future of this technology, according to Lawrence W. Kavanagh, AISI vice president of manufacturing and technology. "What sets molten oxide electrolysis apart from other metal producing technologies is that it is totally carbon-free and, hence, generates no CO2 gases-only oxygen," said Kavanagh. "Over the last two decades, steelmakers have reduced energy utilization per ton by some 28 percent, and today's processes are productive and green, but steelmakers need to and want to do moreand the development of transformational iron making technologies such as MOE will make similar achievements possible over the next two decades as well." TRP started in July 1997 as a partnership between AISI and DOE in order to identify trends, drivers and technological challenges facing the steel industry. The TRP goal is to increase the competitiveness of the U.S. steel industry while saving energy and enhancing the environment. This work by MIT marks one of TRP's breakthrough projects towards meeting that goal. Unlike other iron
making processes, MOE works by passing an electric current through a liquid
solution of iron oxide. The iron oxide then breaks down into liquid iron
and oxygen gas allowing oxygen to be the main by-product of the process. AISI Joins in Unveiling of "My Other Car Is..." Concept VehiclesThis summer, design and engineering disciplines merged as students from College for Creative Studies (CCS) and University of Michigan (U-M) unveiled their remarkable automotive designs for the 18th annual American Iron and Steel Institute (AISI) summer automotive design internship. This year's internship program broke new ground by introducing a real-world twist. Three engineering students joined three transportation design students to produce exhilarating concept vehicles that targeted Generation X, Baby Boomers and the Millennial generation. These concept vehicles embody leading-edge steel technology utilizing a flexible platform. "Developing future generations of cars and training the designers behind the concepts means incorporating advanced materials and safety technology into each design," Ron Krupitzer, vice president for AISI's Automotive Applications Committee (AAC) said. "AISI, together with CCS and U-M, are bringing tomorrow's designers and engineers together in this study to pioneer new steel ideas focused on today's various lifestyles and generations of buyers." This summer the design students learned about the concerns of the engineers, and the engineers learned how to support new design ideas. As a result, the group's understanding and respect for each other's work was enhanced. The concepts evolved through two distinct perspectives to create a harmony of product concept and mechanics. Each student had the opportunity to collaborate in the production of a car and learn about the "rapid to market" concept. Throughout the internship, AISI scheduled field trips for the students to demonstrate behind-the-scenes steelmaking and vehicle manufacturing. Field trips to steel mills, stamping plants, engineering facilities and design studios provided rare opportunities to witness the various production stages involved in creating a vehicle. With guidance from AISI steel-applications specialists and professional automotive designers, students learned the design and engineering potential of steel to increase their understanding of how to work with the material. Perfection of design is reflected in a car's finish. Matrix System Automotive Finishes partnered with the CCS students to provide each student with a supply of paint. While touring the Matrix facility, the students gained insight into paint processing and quality control. Each model now boasts a custom-created paint finish. "The AISI internship allows the students to experience working with flexible manufacturing processes and materials to meet the design requirements shaped by the automotive industry," Bryon Fitzpatrick, chairman of transportation design for CCS said. "Students gain a breadth of knowledge in new steel applications and incorporate design elements that can be used to meet future needs such as safety, affordability, and fuel efficiency." Since 1989, the AISI/CCS
interns have faced design challenges that range from visual appeal to
versatility of application. But whether creating cars from movie themes
or focusing on fuel containers, the students work toward one basic goal:
using advanced steel technologies to design vehicles that are safe, affordable,
fuel efficient and environmentally responsible. For more information,

Steel-framed homes will be in the spotlight at the New Orleans' Housing Solutions Summit today and tomorrow with the display of the 400-square-foot "Cajun Cottage" in the center of the exhibit floor at The Ernest N. Morial Convention Center. Constructed by the Steel Framing Alliance (SFA), a national industry association of steel framing builders, manufacturers, designers and suppliers, the cottage also anchors an area dubbed "Steel Central" where 14 steel framing companies will be concentrated, ranging from builders to suppliers of framing materials.
The Housing Solutions Summit, hosted by the City of New Orleans, the Home Builders Association of Greater New Orleans, The State of Louisiana, and Entergy, is being held on September 29 and 30 and is intended to provide homeowners, renters, leasing agents, contractors, businesses and investors with first-hand information about building technologies and resources that are available to them. Co-sponsors include the U.S. Department of Energy and American Institute of Architects, New Orleans. Admission to the summit is free and open to the public.
"We are excited to be able to officially introduce steel framing to New Orleans because we believe that it is an important solution to some of the challenges of rebuilding strong, durable homes in the Gulf Coast region," says Larry Williams, President of the Steel Framing Alliance. He notes that although steel framing has not been commonly used in Louisiana over the past 10 years, nearly 500,000 homes have been built with steel framing in the U.S., including 70 percent of the homes in Hawaii where issues like termites and mold have had a major impact on the homebuilding industry.
"In addition to the fact that steel framing cannot be eaten by termites and will not provide food for mold, steel won't burn, warp, crack, or split, giving homeowners straight, square walls without unsightly nail pops," Williams adds. "Better yet, steel framing can be designed to withstand hurricane-force winds and is protected from corrosion by a galvanized coating that can last hundreds of years.
"We're excited by this opportunity to show the many benefits of steel framing, and I believe that the exhibitors in 'Steel Central' will demonstrate that steel framing is an affordable and accessible option homeowners should consider," says Williams.
In addition to exhibiting,
SFA will be presenting a 30-minute educational session on Saturday,
September 30, at 1 p.m. to provide homeowners with the basics they'll
need when thinking about steel framing and to give builders some basic
tips on steel framing as a business.
The Steel Framing Alliance and its 1,400 member companies are leading the development of steel framing as an efficient and cost-competitive alternative to traditional framing materials by providing builders and designers with information and resources they need.
SFA, along with 12 steel companies and the Metal Roofing Alliance (MRA), American Iron and Steel Institute (AISI), and Steel Recycling Institute (SRI), is supporting the Gulf Coast Steel Initiative (GCSI). GCSI's collective efforts to help reshape future construction in the region include training code officials on steel framing and roofing best practices, working with the insurance industry to implement Builders Risk and homeowner insurance discounts, and promoting building codes that define state-of-the-art practices for hurricane-prone areas with state and federal legislators. The steel industry is also updating its national recycling database in the Gulf Coast region to list sites where consumers and businesses can bring their steel products for recycling.

According to findings from an omnibus survey conducted by the Canned Food Alliance (CFA) and AISI nearly half of Americans say they've purchased supplies for an emergency. AISI's Steel Packaging Council invests in the CFA to change consumers' perceptions and purchasing behaviors in regard to canned food. With September being National Preparedness Month, the CFA worked with the Department of Homeland Security to develop the survey questions and commissioned the survey of Americans to explore how prepared they are for emergencies. It is important to note that Americans in the West and the South, those most recently affected by earthquakes, wildfires and hurricanes, are more likely than others to say they have bought emergency supplies. The CFA will work with the Department of Homeland Security to inform American families how to stock their pantries with convenient, safe and nutritious canned food.
The survey also found that steel is at or near the top of lists of materials Americans would want to have their homes' doors and frames to protect them from natural disasters. Three-quarters of those surveyed said they would want steel doors for their home.
Of those who have not purchased supplies, procrastination is the top reason for not doing so. More than a third believe they won't be affected by an emergency. Motivating these unprepared Americans will likely happen close to home. The survey found that six-in-10 of those Americans who are unprepared would be compelled to purchase supplies if they received a warning from the local government or if they had a previous experience with disaster.

AISI's Bridge Task Force has named Reagan Herman, Ph.D., as the 2006 recipient of the Robert J. Dexter Memorial Lecture. The program was instituted in 2005 to honor Robert J. Dexter, associate professor of civil engineering at the University of Minnesota. Dexter was an internationally recognized expert on steel fracture and fatigue problems.
The Robert J. Dexter Memorial Lecture provides an opportunity for an individual early in his/her career in structural engineering to present a lecture on his/her steel bridge activities to the AISI Bridge Task Force and to participate in its semiannual three-day meeting. The Bridge Task Force is made up of the United States' leading steel bridge experts.
Herman is an assistant professor in the Department of Civil Engineering at the University of Houston. Her presentation to the AISI Bridge Task Force was on "The Implementation of Permanent Metal Deck Forms as Lateral Bracing for Steel Girder Bridges." She is involved in several studies sponsored by the Texas Department of Transportation, including the implementation of innovative bracing options for steel plate girder bridges, as well as research studies of steel trapezoidal box girder systems, thermal effects on steel bridges, and the impact of geometric imperfections on steel bridge behavior. Herman earned Ph.D. and M.S. degrees in structural engineering from the University of Texas at Austin and a B.S. degree in civil engineering from North Carolina State University.
"The Robert J. Dexter Memorial Lecture was instituted to honor the memory of an esteemed colleague who was dedicated to finding real-life solutions to complicated steel bridge design problems," said Alex Wilson, manager of customer technical services for Mittal Steel USA and chairman of AISI's Bridge Task Force. "The program gives us an opportunity to recognize young bridge design talent and provide a platform for them to develop long-term steel bridge design solutions. We are pleased to name Dr. Herman as our second program recipient, and look forward to the contributions that she will continue to make to steel bridge design."
The first Robert J. Dexter Memorial Lecture recipient was Robert J. Connor, assistant professor of civil engineering at Purdue University in West Lafayette, Indiana, who has now joined the AISI Bridge Task Force and is working on the AASHTO (American Association of State Highway and Transportation Officials) specifications for bridge fatigue and fractures. Honorees of the Robert J. Dexter Memorial Lecture are selected on an annual basis and chosen based on recommendations from the members of AISI's Bridge Task Force.

On September 18, AISI announced that it has published the Direct Strength Method Design Guide, which offers an innovative new approach to the design of cold-formed steel members. Benjamin Schafer, Ph.D., who developed the Direct Strength Method, wrote the guide.
"The Direct Strength Method will redefine the way that engineers design with cold-formed steel," said Delbert F. Boring, AISI's vice president of construction market development. "Previously, there were no provisions for designing cold-formed members with complex cross-sections without performing tests. The Direct Strength Method considers elastic buckling behaviors and enables engineers to predict strength for virtually any configuration of prismatic cold-formed steel members. This method will significantly improve the design of cold-formed steel members."
The guide provides practical and detailed instruction on the use of the Direct Strength Method. It includes a tutorial to help engineers interpret elastic buckling analysis results, and provides prescriptive guidelines and examples for developing beam and column charts. It also includes extensive design examples covering 14 different cold-formed steel cross-sections, under a variety of different loading and boundary conditions, which allow engineers to directly compare results between the Direct Strength Method and conventional design. The guide also provides instruction on how to handle unique situations in the elastic buckling analysis of cold-formed steel members.
The Direct Strength Method Design Guide is available in both print and electronic formats and can be purchased on AISI's e-store at www.steel.org. Four recommended companion resources are also available via the AISI e-store:
