Here are the section planes, looks like both the rebars and stirrups are bonded.



Bottom view of bottom rebar (other line bodies suppressed)



Bottom view of rebars and stirrups (all bodies unsuppressed)



Cross-sectional view of stirrups


Here are the modal analysis performed, I've got 6 zero frequencies, meaning that the stirrups are not connected right? How to solve the problem?
