Possible error in overstrength design for IBC 2021 (ASCE 7-16) and IBC 2024
The seismic overstrength design result notes that "An allowable stress increase factor of 1.2 is used for seismic overstrength load combinations" - This increase factor, per ASCE 7-10 section 12.4.3.3, was removed for ASCE 7-16 and beyond.
Thanks for your inquiry. We were able to confirm that the details for this increase factor were not removed for ASCE 7-16 and newer, but moved to section 2.4.5 for both ASCE 7-16 and ASCE 7-22.
Thank you Ian, I had spent what seemed like forever looking for this and couldn't find it anywhere! I'm glad to see that it still exists.
