Instability Warning on a Fully Braced Platform
Instability Warning on a Fully Braced Platform
(OP)
I'm designing a fully braced platform (braced vertically on both X and Z directions, beams released for My and Mz, columns having pinned supports). I know that this structure can stand but how can I eliminate the instability warning?
Thanks a lot.

This is telling STAAD that a VERY small moment can be acheived at the supports. In reality, this is true. You could apply a small moment to a "pinned" support, and have no rotation.
This prevents any instabilities because all degress of freedom are resisted.
