Problem Description
When a foundation supports a braced frame and the brace is one that spans across intermediate stories (modeled using Layout - Brace - Add Special) then the resultant reaction from the brace is absent in the foundation loads giving an unconservative design.
Reason
The program is not seeing the brace when determining the foundation loads.
Solution
The issue will be resolved in the release after v15.03.00. In the meantime, either revert to the prior version 15.02.00.00, or modify the braces so that they intersect a few inches above the base. This can be accomplished by re-modeling the braces using the "knee brace" standard configuration or by adding an extra short story at the base with only columns (and foundations) modeled.
