SAFE: No Negative Moments on Continuous Beams?

SAFE: No Negative Moments on Continuous Beams?

SAFE: No Negative Moments on Continuous Beams?

(OP)
I am modelling a pile supported suspended slab on grade beam foundation. When I look at the grade beam bending moments, all the beams appear to be simply supported. I have tried every combination of line element between piles and I cannot get negative moments in the beam. Yes - I have checked the fixity on the line element and there are no releases set. Any idea what I am doing wrong is this a program limitation?
