Do you design or detail steel bridges? Crane supports for industrial buildings? Cyclically loaded structures like sign supports or luminaries? Or maybe you fabricate cyclically loaded structures? If so, this short course on the design of cyclically-loaded welded connections is for you. This half-day program will review the causes of fatigue crack initiation and propagation, discuss the role of stress range, and explore the performance of various welded connection details. Using the methodology detailed in AISC 360 Appendix 3, the influence (or the lack thereof) of maximum stresses, minimum stresses, and the strength of the steel will all be reviewed. The interaction of fatigue and fracture will be discussed, as will be the constraints associated with the Appendix 3 methodology. Attendees will learn how to design welded connections that will be fatigue-resistant, regardless of the type of structure or source of cyclic loading. This course will be presented by Duane Miller, one of the worlds leading authorities on the design of welded structures and a renowned lecturer. Duane is also a member of the AISC Specifications Committee and has been a major contributor to the content of Appendix 3 over the past 15 years. He currently serves as First Vice-Chair of the AWS D1 Structural Welding Code Committee and Chair of the Seismic Welding Subcommittee. He is a former co-chair of the AASHTO-AWS D1.5 Bridge Welding Code Committee, a member of the AISC Specification Committee, a Professional Engineer, a Certified Welding Inspector, and a Qualified Welder.

SSRC Short Course: Nonlinear Structural Analysis Methods Used in Modern Steel Design

Tuesday, April 21 | 1:00 p.m. - 5:00 p.m.
Speaker: Barry T. Rossen, PE, PhD -- Florida Atlantic University


$275 members* | $400 non-members (Add $50 if purchased on-site.) *Members of the following organizations qualify for a member rate: AISC, NSBA, SSRC, NISD.
Registration is required for this short course. Registration opens January 20, 2020. 

Per Chapter C of AISC's Specification for Structural Steel Buildings, second-order effects, geometric imperfections, and stiffness reductions due to inelasticity and residual stresses must be considered. Modern-day software programs are capable of analyzing these conditions, but designers who use them need to have a fundamental understanding of how these nonlinear analyses are completed, which elements of structural behavior are included and which are neglected, and the degree to which various methods of analysis have inherent limitations that can affect solution accuracy and consistency.

This course will provide an overview of:

  • Modeling geometric imperfections directly versus with notional loads
  • Equilibrium in the deformed configuration using an incremental second-order analysis approach versus the approximate amplification methods in Appendix 8
  • Elastic critical load analysis versus alternate methods to determine effective length factors
  • Inelastic behavior and analysis of steel beams and frames
  • Analysis of alternating loads that produce shakedown and incremental collapse conditions
