For several editions, AISC maintained separate manuals for ASD and LRFD. However, the landmark 13th Edition, released in 2005, unified these two methodologies into a single, cohesive framework. Subsequent versions—the 14th Edition (2011), the 15th Edition (2017), and the current 16th Edition (2023)—have continued this unified tradition, incorporating updated specifications and refined design tables to keep pace with modern engineering practices.
