The New ASTM A1085 Specification:
A New Dynamic for HSS
With the adoption of the new ASTM A1085 specification in early 2013, Hollow Structural Sections (HSS) produced to a higher standard are now available. This new manufacturing standard raises the bar on the performance of HSS used in structures subjected to seismic and fatigue related loads. With tighter material tolerances, a higher minimum yield stress, a required Charpy V-Notch test, and cap on the minimum yield stress, this new specification makes designing with HSS easier and more economical, especially for buildings and bridges subjected to fatigue and seismic loads. This session will cover the history and development of the new spec as well as show how economical HSS can be through design examples.
Biography of Presenter:
Brad Fletcher, S.E., is the senior sales engineer at Atlas Tube. In this role, Brad leverages his 24 years of experience in engineering design and the steel industry to provide technical expertise on the use of steel hollow structural sections (HSS) and pipe piling products to design engineers, detailers, fabricators and architects. A registered structural engineer in the state of Illinois, Brad has held senior positions at leading architecture and engineering firms, Skidmore, Owings & Merrill; Sargent & Lundy; and Halvorson and Partners. For the past eight years, most recently while working at Tata Steel (formerly known as Corus) and now with Atlas Tube, Brad has focused his efforts on serving as a liaison between structural designers and the steel industry. Brad holds a Bachelor of Science and a Master of Science in civil engineering (BSCE, MSCE) from Purdue University. He is active in many industry groups, including the American Institute of Steel Construction (AISC), the Structural Engineers Association of Illinois (SEAOI) and ASTM International. Brad is active within AISC, participating in the Technical Committees responsible for the AISC Specification, as well as the HSS Producers Group. Brad is also on the Board of the CISC Education and Research Council (formerly SSEF) in Canada and the
S16 Technical Committee for the Canadian Standards Association (CSA).
