V. AISC 360-22 W Section Classification
Verify the section classification of a wide flange section per the AISC 360-22 code.
Reference
- Steel Construction Manual, 16th Edition, American Institute of Steel Construction, 2017
- Design Examples, Version 16.0, American Institute of Steel Construction, 2017. pp
Problem
A 3' long, simply supported beam is subject to an axial load of 15 kips. The section is a W6x15. The material is grade 70 ksi steel.
Section Properties
From reference #2:
- Depth, d = 5.99 in
- Flange thickness, tf = 0.260 in
- Web thickness, tw = 0.230 in
- Flange + fillet distance, kdes = 0.51 in
- b / 2tf = 11.5
- h / tw = 21.6
Calculations
Element Slenderness - Compression
Flanges (Table B4.1a, case 1):
λf > λrf, so the
flanges are slender
in compression.
Webs (Table B4.1a, case 5):
λw < λrs, so
the webs are nonslender
in compression.
Element Slenderness - Flexure
Flanges (Table B4.1b, case 10):
λpf < λf <
λrf, so the flanges are noncompact
in flexure.
Webs (Table B4.1a, case 15):
λw < λps, so the
webs are compact
in flexure.
Comparison
| Result Type | Reference | STAAD.Pro | Difference | Comments |
|---|---|---|---|---|
| Flanges in compression | slender | slender | none | |
| Web in compression | nonslender | nonslender | none | |
| Flanges in flexure | noncompact | noncompact | none | |
| Web in flexure | compact | compact | none |

*** AXIS CONVENTION ***:
========================
The capacity results and intermediate results in the report follow the notations
and axes labels as defined in the AISC 360-22 code.
The analysis results are reported in STAAD.Pro axis convention and the AISC 360:22
design results are reported in AISC 360-22 code axis convention.
AISC Spec. STAAD.Pro Description
------------ ----------- -------------
X Z Axis typically parallel to the sections principal major axis.
Y Y Axis typically parallel to the sections principal minor axis.
Z X Longitudinal axis perpendicular to the cross section.

AISC Spec. STAAD.Pro Description
------------ ----------- -------------
Pz FX Axial force.

Vx FZ Shear force along major axis.
Tz MX Torsional moment.
My MY Bending moment about minor axis.
Mx MZ Bending moment about major axis.
*** DESIGN MESSAGES ***:
=======================
1. Section classification reported is for the cross section and loadcase that
produced the worst case design ratio for flexure/compression Capacity results.
2. Results for any Capacity/Check that is not relevant for a section/loadcase
based on the code clause in AISC 360-22 will not be shown in the report.
3. Bending results are reported as being "about" the relevant axis (X/Y), while
the results for shear are reported as being for shear forces "along" the axis.
E.g : Mx indicates bending about the X axis, while Vx indicates shear along
the X axis.
