SIR (Section Result) for quad elements in DYNA

Hello, I have a question about SIR (Section Result) in DYNA.
I try to get the M,Q,N results at the base of a shear wall (quad elements) for an Earthquake loading.
I have put a vertical loading 1000kN/m on a 5m long shear wall (1m thick and 5m tall) and the results of Earthquake analysis are stored in LC 902.
When I cut the wall base using SIR there are no Moment or Axial forces in the Result file.
