Hi guys,
When i have a solid slab ( drops + beams) with edge beams, and when i assign to the beams no torsional stiffness so the slab can handle the torsion, i have a warning in the safe run analysis : "structure unstable or ill conditioned", i dont understand why. There is a torsion compatiblity so i can report the torsion from the beam to the slab.
What i am intending to do is to take each part of the slab and assign its adjacent beams 0 torsional stiffness so i can analyse it. And then, i make the same procedure for the other edge beams. Do u think this is appropriate ??
Many thanks
