NASA’s Jet Propulsion Lab. The second keynote features Duane Miller, P.E., ScD, manager, engineering services and welding design consultant at Lincoln Electric. In his talk, Important Lessons I’ve Learned During the Past 40 Years, Miller will cover topics ranging from the value of mentorship (both as a mentor and as a mentee), leadership principles, welding and welded connections, steel and steel behavior, life lessons, troubleshooting, and developing customers for life. The third keynote is the 2018 T.R. Higgins Lecture, in which the 2018 award winner, Robert J. Connor, a professor at Purdue University School of Engineering, will address the topic, Towards an Integrated Fracture- Control Plan for Steel Bridges. There has been considerable research and interest in the topic of fracture-critical members (FCMs) during the last decade. As a result, the entire concept of what constitutes an FCM is being revisited and many long-standing ideas and opinions related to this classification of members is being shown to be overly conservative. Significant advances in the understanding of fracture mechanics, material and structural behavior, fatigue crack initiation, fatigue crack growth, fabrication technology, and inspection technology have allowed other industries to address fracture in a more integrated manner. After years of research, new stand-alone AASHTO-ready guide specifications have been proposed that give codified direction on how to perform 3D system analysis to verify system redundancy, as well as guide specifications to evaluate internal member-level redundancy of mechanically fastened built-up members.
Additional research demonstrating the benefits of exploiting the improved toughness of modern HPS grades of steel has been completed. Through these advances, it is now possible to create an integrated fracture control plan (FCP), combining the original intent of the 1978 FCP with modern materials, design, fabrication, and inspection methodologies. The World Steel Bridge Symposium, with 25 presentations, brings together bridge design engineers, construction professionals, academics, transportation officials, fabricators, erectors, and builders to discuss and learn state-of-the-art practices for enhancing steel bridge design, fabrication, and construction techniques. The Structural Stability Research Council’s Annual Stability Conference includes 13 sessions with more than 30 papers, as well as the 2018 Beedle Award and McGuire Award for Junior Researchers (MAJR) Medal presentations. Detailed information about all of the sessions and conference registration is available at www.aisc.org/nascc.

Thewebinar will be conducted byDonAllen, P.E., director of engineering for Super Stud Building Products, Inc. He oversees product development, testing, engineering, and technical services. Allen has worked in the cold-formed steel framing industry since 1990 as a cold-formed steel specialty engineer, engineer-of-record, industry representative, and trade association technical director. He is chairman of the Education Subcommittee of the American Iron and Steel Institute’s Committee on Framing Standards and Committee on Specifications. He was the 2013 recipient of the CFSEI Distinguished Service Award. More information on the webinar and registration are available at www.cfsei.org/webinar-february-22-2018.
Change orders and cold-formed steel CFSEI to host webinar for architects, engineers, building officials, and contractors.
The Cold-Formed Steel Engineers Institute (CFSEI) will host a webinar on “Change Orders and Cold-Formed Steel” on Thursday, Feb. 22, 2018 at 3:00 p.m. ET. The webinar is designed for architects, engineers, building officials, and contractors. Participants are eligible for 1.5 PDHs. The webinar will cover several relevant topics, including: • issues that lead to change orders; • how architects, engineers, and general contractors can avoid them; • how carpenters and subcontractors can benefit from them; and • a review of contract language and documents that can influence change orders.
