Curved Steel

With the increased exposure curved steel is finding in the marketplace, questions continue to arise about processes, possibilities, and producers. The curved steel section provides several resources to answer these questions and more: 

  • Who curves steel?
  • Where can you use curved steel?
  • How do I specify curved steel?



AISC Bender-Roller Committee

The mission of the AISC Bender-Roller Committee, which is made up of AISC associate member bender-rollers and associated companies, is to increase the use of curved steel in construction while supporting AISC’s goal of making steel the material of choice.

Design Guide 33Design Guide 33: Curved Member Design

Design Guide 33 is an excellent resource that provides design guidance and practical information on the fabrication and detailing of curved members as well as behavior during the bending operation. It also provides design methodology for vertically and horizontally curved members that is compliant with the 2016 AISC Specification for Structural Steel Buildings. Connection design is discussed as well as stability and serviceability concerns. It also includes detailed design examples.
