Purlin under concrete slab

Hi Rafal

 

Please find the attached file. How can I place purlin under concrete slab. What does dsb mean in Frame Generator. I supposed that dsb is the spacing between purlins or I'm wrong.

 

The calculation displays instability in UX direction on node 40. Why is that and how can I solve it in construction and analytically?

Ignore it or use Skyline solver.
