Problem Description

Design for Tee Sections as per AISC 360-05/10 for which critical condition is  H2-1 is not correct as software is not considering the correct section modulus..

Steps to Reproduce

1. Analyze and design a model with Tee section for which H2-1 is governing criteria.
2. In the analysis file, note that the allowable bending stress uses the incorrect section modulus.

.

Workaround

None

Solution

This has been addressed in 20.07.11.70.

The AISC 360-10/05 steel design routines have been updated to correct the calculation of stress for bending about the local Z axis of Tee sections.
