Abstract:
Only three sections in Chapter 18—Earthquake-Resistant Structures of ACI 318-19 remain unchanged in comparison to ACI 318-14. This is the second of two articles that outline these changes and is focused on special structural walls, diaphragms and trusses, foundations, and members not designated as part of the seismic force-resisting system.
