(Review Period: September 9, 2024 - October 21, 2024)

Instructions for Comment Submittal

The next edition of AISC 358, currently slated for a 2027 release, will supersede ANSI/AISC 358-22.

This draft includes:

• General updates to bolting requirements in applicable chapters.
  
  
• Chapter 6 (End Plate) updates to the bolt shear and bearing/tearout check to be consistent with the AISC Specification. The welding requirements for moderately ductile built-up sections have also been updated to alleviate the susceptibility to brittle fracture.
  
  
• Chapter 10 (ConXtech ConXL) updates to the collar bolt specification and other miscellaneous updates.
  
  
• Chapter 12 (Simpson Strong-Tie) and Chapter 15 (DuraFuse Frames) updates that expand each connection’s prequalification limits.

Please submit comments with reference to the applicable section, page number(s), and line number(s). Please provide alternative specification language that would resolve any objections, if possible.
