Problem
A C15x33.9 section is subjected to an axial dead load of 4 kips and live load of 10 kips. Assume a shear lag factor of U = 0.8 and a net area of 90% of the gross area due to the connections. The material is Grade 70 steel.
Section Properties
From reference #2
- Gross area, A = 10.0 in2
Calculations
Section Forces
This example will use a single load case for both LRFD and ASD examples: 1.0DL + 1.0LL.

========================
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.

*** 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.
