Problem Description

When multiple tapered members are designed in group with CHECK CODE ALL command vs. designed individually, the design results do not match. Noted for multiple codes like AISC 360-05/10 / IS800-2007/ S16- 09/14.

Steps to Reproduce

Run an appropriate model with Tapered member and check the results of design for the two cases
a. using an individual CHECK CODE for each member
b. using a CHECK CODE for a LIST of members
Results seem to differ.

.

Workaround

The only option for now is to design these tapered members individually using CHECK CODE MEMB ... command
