Despite the widespread use of curved structural steel members, detailed guidance relative to United States design practice is scarce. 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. Detailed design examples are included.
