Problem Description

The compression flange yielding capacity determined in AISC 360-05 or 10, Section F4 for qualifying sections was incorrectly determined. 

Reason

Where the governing capacity for sections evaluated under Section F4 "Other I-Shaped Members with Compact or Noncompact Webs Bent about their Major Axis" was the Compression Flange Yielding limit, the reported capacity was incorrectly determined as Fy * Zx rather than Rpc * Fy * Sxc per Equation F4-1. 

Solution

The issue will be resolved in the release after v15.03.00.
