Design of Curved Members -- A Two-Part Webinar Series

While curved members can be both structurally efficient and aesthetically interesting, their behavior can be much different than their straight counterparts.  This two-part webinar series, presented by the author of AISC Design Guide 33, Curved Member Design, provides guidance on how to use the AISC Specification to design curved members.  This 'equivalent straight member' approach allows the use of existing commercial software for curved member design by modifying effective length factors and lateral-torsional buckling modification factors to account for the curvature.  This course will provide a brief overview of the design guide and detailed design information on both vertically- and horizontally-curved members.

Part 1:  Design of Vertically-Curved Members

This session will review the design of vertically-curved members for axial, flexural, and combined loading.  A special buckling limit state, unique to vertically-curved members, will be introduced.  Finally, the concepts will be illustrated with a design example.  (Session page)

Part 2:  Design of Horizontally-Curved Members

This session will examine the behavior and design of horizontally-curved members.  The design of such members for flexural, torsional, and combined loading will be explained, as will the important issue of serviceability.  The concepts will be illustrated with a design example.  (Session page)

Interested in learning about the fabrication of curved steel members?  Although this two-part webinar series will focus on the design of curved members, you can also check out a related on-demand presentation, given by Bo Dowswell, recorded from a past Night School course!  The on-demand session covers issues such as curving mechanics, fracture during bending, distortion, tolerances, and more.
