MONDAY SESSIONS SCHEDULE

Even with decades of wide-scale use, projects involving cold-formed steel framing still involve many parties who may not be aware of what their responsibilities are in the design and construction process of CFS framing. 10 years ago, the American Iron and Steel Institute published the first ever Code of Standard Practice for Cold-Formed Steel Framing, a document who’s goal was to answer the question “Who is responsible for what?” In 2015, the newest version of this document will be published, including many new and exciting added sections that deal with matters such as wall panel design, assembly and installation and coordinating steel deck with CFS framing. Coordination with steel deck is a topic that was first brought to the forefront during a panel discussion at a CFSEI expo several years ago and CFSEI members were active in the development of this new section.

Jeff Klaiman has over 20 years of experience in the construction industry includes building maintenance and engineering, on-site engineering for a concrete contractor, Manager of Technical services and Versa-Truss Product Manager for Dale/Incor (national manufacturer of cold-formed steel framing products and systems), participation in multiple committees of the American Iron & Steel Institute’s Committee on Specifications for the Design of Cold-Formed Steel Structural Members and Committee on Framing Standards, Light Gauge Steel Engineers Association for more than 10 years, ASTM International and the Steel Framing Alliance. Mr. Klaiman serves as chairman of the Standard Practices subcommittee of the AISI Committee on Framing Standards and is also the president of the Mid-Atlantic Steel Framing Alliance as well as a past president of the Cold-Formed Steel Engineers Institute. In his position at ADTEK Engineers, Inc as Principal in Charge of Specialty Engineering, Mr. Klaiman oversees the design and coordination of all cold-formed steel design documents. He also manages all in-house staff in 3 offices for cold-formed steel framing design, develops project schedules, and coordinates quality control reviews with project managers on his team. Mr. Klaiman holds a degree in Civil Engineering from the University of Michigan, and a Masters of Business Administration from Eastern Michigan University.

Cold-formed steel members and connections are to be in good condition.  Good condition as defined by the North American Standard for Cold-Formed Steel Framing – General Provisions (AISI S200) includes properly fabricated holes, copes, and splices, proper screw installation, and adherence to manufacturing tolerance.  However, if the member or connection does not comply with the design expectations, remediation or material replacement must be considered.

How to address anomalies in the field condition of a member or connection are common Hotline questions.  This talk will summarize some of the questions and possible solutions.

Dr. Roger A. LaBoube is Curator’s Teaching Professor Emeritus of Civil Engineering, Director of the Wei-Wen Yu Center for Cold-Formed Steel Structures at the Missouri University of Science & Technology (formerly University of Missouri-Rolla). Dr. LaBoube holds B.S., M.S., and Ph.D. in Civil Engineering from the University of Missouri-Rolla. Dr. LaBoube has an extensive background in the design and behavior of cold-formed steel structures. His research and design activities have touched on many facets of cold-formed steel construction to include: cold-formed steel beams, panels, trusses, headers, wall studs as well as bolt, weld, and screw connections. Dr. LaBoube is member of the American Iron and Steel Institute’s Committee on Specifications for the North American Specification for the Design of Cold-Formed Steel Structural Members and a member of the AISI Committee on Framing Standards. He is a Registered Professional Engineer in Missouri.

2:45 P.M. - 3:30 P.M. BREAK IN EXPO HALL

Building codes include acoustic requirements for assemblies separating occupancies. Currently this is based on the direct transmission of sound through the wall or floor defined by the Sound Transmission Classification (STC). A multi-unit residential cold-formed steel framed building can have different occupancies stacked vertically and horizontally. While the STC rating classifies the direct transmission through the wall (or floor), it does not capture the flanking transmissions that travel through the ceiling-wall-floor intersections. Research has shown that the flanking transmissions can be significant and a primary cause for tenant noise complaints.

Building codes are recognizing the importance of controlling flanking transmissions and are starting to impose Apparent Sound Transmission Classification (ASTC) limits on assemblies. The 2015 edition of the National Building Code of Canada will require an ASTC of 47 or greater. The US green codes are expected to follow suit in the future. The problem for the North American steel industry is that there are no available ASTC values for cold formed steel framing.

The industry has begun a research program at the National Research Council of Canada in Ottawa, Ontario to address this problem. Testing began in June of 2014 with a series of direct transmission tests on structural cold-formed steel walls and floors. Parametric studies were carried out to determine the impact of varying the member spacing, depth, thickness, sheathing type, number of sheathing layers, cavity insulation and resilient channels. The next step will be the flanking transmission tests, beginning in March 2015. The entire project is expected to be completed early in 2016.

The objective of the presentation will be two-fold: present the results of the direct transmission tests including the parametric studies; and give an overview of the flanking transmission testing scope.

Dr. Fox received his civil engineering degrees (B.A.Sc., M.A.Sc., Ph.D.) from the University of Waterloo, business degree (MBA) from York University and history degree (BA) from Waterloo. He has over 30 years of industry experience with the Canadian Sheet Steel Building Institute (CSSBI). The CSSBI is the national association representing the structural sheet steel building industry in Canada. The Institute develops product standards, technical information bulletins, conducts educational and promotional seminars, sponsors research, provides technical assistance, and represents the industry to government agencies and other user groups. The responsibilities of Dr. Fox, as the General Manager, cover administrative duties, managing all of the technical and promotional programs for the Institute, and acting as the representative of the steel industry in numerous venues. Dr. Fox is also founder and President of Structural Testing and Research Inc. (STaR) located in Cambridge, Ontario. STaR is an ISO 17025 accredited testing laboratory specializing in cold-formed steel structural members.

BIM is more than a 3-D Model What it isn’t. What it is. What it can be.

An overview of 3-D Modeling “Best Practices” relating to LOD (Level of Development), Model Element Ownership and Model Sharing will be discussed. The presentation will take attendees through the process of inputting CFS shapes into a REVIT model using third party software to accomplish this task. They will also be shown how to leverage the “I” in BIM creating shop drawings from the model and on to the next information level of fabrication by using CNC Modules that communicate between the model and cold formed steel roll formers.
