Here’s a concise guide to the AISC 325 Steel Construction Manual (often referred to as the AISC Manual of Steel Construction).

Part 10 through 15 focus on Connections, which is where the real "art" of steel happens. aisc 325 steel construction manual

The current standard is the 16th Edition (AISC 325-23), released in 2023, which supersedes the 15th Edition (2017). Core Purpose and Contents Here’s a concise guide to the AISC 325

Final Warning: Always confirm which edition is adopted by the Authority Having Jurisdiction (AHJ) for your specific project. When in doubt, default to the latest edition (currently 16th Ed.), but keep a copy of AISC 325 for legacy work. LRFD (Load and Resistance Factor Design) – uses

LRFD (Load and Resistance Factor Design) – uses factored loads, strength reduction factors (φ)
ASD (Allowable Stress Design) – uses service loads, safety factors (Ω)

The AISC 325 Steel Construction Manual is the definitive authoritative reference for the design, fabrication, and erection of structural steel in the United States. Published by the American Institute of Steel Construction (AISC), this manual serves as the primary resource for structural engineers, detailers, and fabricators.

Coping and hole patterns: use the Manual’s specific modification procedures and reduced section tables (e.g., coped beams).
Composite design: follow composite member tables and composite connection guidance; confirm slab dimensions, concrete strength, and shear connector assumptions.
High-strength steels and HSS: use updated W/HSS tables when working with 65–70 ksi or Grade C HSS — check that the Manual edition includes those tables.

Parts 3-5: Flexure, Compression, and Tension Members

The holy trinity of member design. Each part walks you through limit states: yielding, rupture, block shear (tension); flexural buckling, torsional buckling (compression); and lateral-torsional buckling, flange local buckling (flexure).
