ETABS CENTRE OF RIGIDITY 1

[engineer327]

Hello,
I am trying to obtain Centre of rigidity for a 2 storey frame in 2D. However in the "SHOW TABLES > ANALYSIS RESULTS > STRUCTURE OUTPUT > OTHER OUTPUT ITEMS > CENTRES OF MASS AND RIGIDITY", only Centre of mass is displayed. Centre of Rigidity is not displayed. Th

e Etabs model is attached for reference.
How can I resolve this issue?
Thanks in Advance!!!

I believe that you need to assign the diaphragm as "rigid" and then tick the box in the "set cases to run" (btm left hand corner).
