From dyn run output for frequencies and generalized mass,
Please advise how to derive the Eigenvalue, is there any specific formula, where frequency is 1 / period.

Hi Wong Kee Luen,
Thank you for your question.
If you are wondering about the eigenanalysis procedure, I would like to recommend referring to the textbook such as Dynamics of Structures by Chopra or just google it. You will get tons of information. Please let me know if I misunderstand your question.
Best regards,
Bitna
