From Results menu >> Stories >> Values' tab ... You will find table of G & R for each story .
This picture shows .
And this is how you can view the centre of rigidity and centre of gravity on your model.
Results -> Diagrams for buildings -> Forces
Hi, the checkboxes for center of gravity, rigidity and mass are locked to me in the table of Stories Results. Is it possible that I am missing something before calculations
Thank you for your help
Thank you @cdmatheus, I had already defined stories but no worries I have known my mistake I did not see the values tab
I have another question regarding residual mode for seismic calculation
I have made a modal analysis for a five story reinforced concrete building based on the UBC97 code
The mass participation for X & Y directions is about 73% and the frequency is about 33 (no significant change in these results from mode number 30 to mode number 40)
I have read that for such case residual mode should be used for seismic analysis, but it seems that it is not available for UBC97. What should I do in this case
My assumption is that this question was answered by @mustafahesenow (thank you) in this topic:
Is this correct?
