ACI 318-19 Changes to the Concrete Design Standard-Walls

Video Transcription

Video Summary

Larry Novak, Chief Structural Engineer for the International Code Council, discusses key updates in ACI 318-19 regarding wall design. The scope has been expanded to include cantilever retaining walls within the Foundation Chapter and emphasizes wall failure modes such as shear and flexure. The new section 11.1.6 permits cast-in-place walls with insulated forms for one- and two-story buildings, aligning with ACI 318 and additional guides like ACI 560-R and PCA 100. Changes also include simplified bar placement rules for walls over 10 inches thick and reinforced protocols for openings in plain concrete walls.
