center of rigidity calculations

[memoalcr]

In the following model I agree with the center of mass calculations; however, the center of rigidity seems off specially in stories (it shifts to the right - towards grid x9 - drastically) Look at Stories 2, 3, and 5.

Please advice on how to correct this issue

Thank you for your reply

Thank you for your comments.

1. I don't know what line 16 is
2. For the comment "Is there something here ?" This is an opening for the parking level
3. I am not really sure how to  read the information in EXP.pdf. I have redefined the geometry of the claddings and bars mentioned in the file
4. I have updated and resubmitted the .rtd file to the post
