Time-history analysis using substructures with ABAQUS

Hello,
I'm trying to use substructures to model a tall building under earthquake load. One floor is created with a substructure and the building is the pileup of a certain number of substructures. I would like to get the time history variation of fields outputs such as S and U. In my substructure definition, I have a frequency extraction step (to add generalized DOF) and a preloading step, I also ask for the damping matrix and the reduced matrix of the substructure, according to Abaqus documentation. I only get the output for the last increment, would you have any suggestion?
Thanks in advance

Ok I figured out... you just have to specifiy to combine all the frames in the substructurecombine plugs-in.
