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).
Instead of calculating section properties and executing multi-variable equations by hand, engineers utilize the Manual’s "Z-table" (Part 3) to pick beams based on required plastic section modulus ( Zxcap Z sub x ) and unbraced length ( Lbcap L sub b

Hanger connections, bracket plates, and eccentric bolt/weld groups. Part 16: Specifications and Codes
You can look up the exact shear and tensile strength for various bolt diameters (like the common 3/4-inch A325) without doing the math from scratch.
