Hi,
Can anyone please advise me how to graphically show the various mode shapes after a modal analysis.
The result - diagrams-deformation tab displays only the 1st mode shape.
Also, can anyone comment please on whether the expected number of modes for a 4 level concrete shear wall building would be in excess of 10?
My model does not seem to be able to hit 90% mass particiaption during a modal analysis within 10 modes. Needs closer to 200!!
Help!

You need to select them from the list

Most likely you have a lot of local vibrations of small parts of the structure.
