rotation of master node in rigidDiaphragm and record

[ashf]

hi,
my model is a 3D 5-sory steel braced structure.I do push analysis.when I fix rotation of master node in rigidDiaphragm around axis of vertical,it is run completely,but
when I allow the rotation, it faces many problems to converge.why?
an another case causing convergence,the case I use elastic material for braces!!

what is problem exactly?

1-
fix 1335 0 1 1 1 1 1
fix 1334 0 0 1 1 1 0
fix 1333 0 0 1 1 1 0
fix 1332 0 0 1 1 1 0
fix 1331 0 0 1 1 1 0

OR

fix 1335 0 1 1 1 1 0
fix 1334 0 0 1 1 1 1
fix 1333 0 0 1 1 1 0
fix 1332 0 0 1 1 1 0
fix 1331 0 0 1 1 1 0




2-
fix 1335 0 1 1 1 1 0
fix 1334 0 0 1 1 1 0
fix 1333 0 0 1 1 1 0
fix 1332 0 0 1 1 1 0
fix 1331 0 0 1 1 1 0

as another question,I record reaction of nodes at base of columns and sum them with reaction of nodes of first story braces to calculation of shear base,is it correct?

thanks if any body helps me!

1- Release constraint of node 1335 in both X and Y directions.
2- It's correct if you define separate nodes for braces.
