Modal Analysis of multiple beams

[mmagg]

I have a design where I have three cantilever beams that act together to support a centrifugal blower. I need to find the natural frequency of the three beams. How do I tell ansys that these three beams act as one?

P.S. All three beams are supported along the same point and I have given a zero value to the DOF at these points.

Anyones input would be appreciated.

Thanks, Mike.
