Hi Peter,

 

Thank you so much for the reply! I just performed a Modal analysis, and it does not seem very off (graph attached for the 12th modes - 3.2499Hz); also, the participation factors seem fine. Since the same problem still persists, may I ask if it could be because of material properties? I changed many combinations to try to address this. I am now using "Structural Steel" for all beams and "Concrete" for all solid bodies. Both materials are from Ansys General Material.


Again, thank you.

 

Best,

Ted
