Eg. I consider the below building, beams and columns size are 300x300mm. In addition 2kn/m2 floor load is considered on all floors.
Using "Print Dia CR" command , staad is showing the below result
How the rigidity is changing on each floor as the beams,column & loads applied is same?
What are the parameters considered for calculating stiffness?Usually if we are doing manually, stiffness of column alone will be used for calculating the stiffness/rigidity on each floors.
Please explain how the above calculation has been made.
(Above Example is taken from STAAD.Pro CE – Seismic Analysis Using IS 1893 (Part 1):2016 problem statement 10.1)
Please refer to the following wiki for computation of CR-

I need to have the model attached here to check it.

Hi sanju
Thanks for your reply.I checked the link which u shared but didnt get the calculations of RXY,RZY,RYY.
Anyway if possible please explain how the centre of rigidity calculation has been made in the attached STAAD file.
Thanks in advance.
anyone there to help?
anyone from bentley can answer?
I suggest you raise a service request.
