Question:
please see the attached model
Answer:
Hello,
Those error is because of duplication of Rigid link and diaphragm. Rigid link cannot be duplicated with the diaphragm, so please change the "consider --> do not consider" in Floor diaphragm via structure > building > Control data > Story data.
Or if you want to consider the Floor diaphragm, use elastic link instead of rigid link.
Thank you.
Best regards,
Jihong Hwang
