Dedicated to beam design, this section contains tables for selecting members based on plastic moment, buckling limits, and deflection.
The manual prints design tables with side-by-side solutions: , while ASD values are shaded in green (or designated clearly in text), allowing engineers to use either method seamlessly. Anatomy of the Manual: Part-by-Part Breakdown
As of mid-2024, AISC released the 16th edition (AISC 326). However, many jurisdictions and exams still reference (15th ed). Here is what changed:
Introduced standard allowable stresses and consolidated dimensions for shapes produced by various mills. aisc 325 steel construction manual
Lists the physical characteristics (like weight, depth, and area) of standard structural steel shapes such as W-shapes, channels, and angles.
This part covers structural elements subject to axial pulling forces, such as bracing and truss members. It guides engineers through calculating tensile yielding on the gross section and tensile rupture on the net section, while accounting for shear lag factors ( Part 6: Design of Members Subject to Combined Forces
When a steel frame undergoes lateral displacement, gravity loads act on the displaced geometry, generating secondary bending moments. The manual provides systematic techniques (such as the B1cap B sub 1 B2cap B sub 2 Dedicated to beam design, this section contains tables

Furthermore, the Manual facilitates the principle of . The AISC publishes "Critic al Shapes" lists within the manual, indicating which steel shapes are most readily available from U.S. mills. An engineer ignoring this list may specify a beam size that is technically sound but unavailable or exorbitantly expensive, causing project delays. By adhering to the Manual’s guidance, engineers optimize the balance between material weight (cost) and labor (fabrication cost).
