Professional AISC 360-16 Analysis
Design your structural steel members with confidence using our AISC 360-16 compliant calculator. This tool evaluates member stability, local buckling, and combined interaction ratios for complex loading scenarios.
Core Design Methodology
Our engine implements the Specification for Structural Steel Buildings (AISC 360-16), covering both LRFD (Load and Resistance Factor Design) and ASD (Allowable Strength Design). The calculator handles the geometric classification of sections into Compact, Noncompact, or Slender categories, which is essential for determining bending and compression capacities.
Clause Compliance Coverage:
- Chapter D: Tension member yielding and rupture.
- Chapter E: Flexural and Flexural-Torsional buckling for compression members.
- Chapter F: Lateral-Torsional Buckling (LTB) and Flange/Web local buckling for flexure.
- Chapter G: Shear strength of members.
- Chapter H: Combined force interaction for axial force and biaxial bending.
When to use ASD?
ASD is preferred for foundation design and when coordinating with legacy codes. However, LRFD provides a more uniform reliability across different load combinations and is the modern standard for building design.
What is Lb?
Unbraced length (Lb) is the distance between points braced against lateral displacement or twist. A high Lb drastically reduces bending capacity due to Lateral-Torsional Buckling.
