Dear Kags,
From your STAAD analysis, you will get bending moments and direct forces per metre length at each node of each element. You could resolve these in two perpendicular directions, and then design the reinforcement in these two directions as per your local code of practice. While doing this, remember to add half of the torsional moment Mxy to the bending moment in each direction.
