Modal analysis and shell element

[MohammadZaman]

Hello.

I modeled a concrete shell element and I want to get the shear force produced due to modal shapes. When I run the modal analysis there is no result . Could you please help me?

Thank you.

Modal shape is unrelated to internal forces and as such you can't view them.  

You need seismic or spectral etc to achieve that.........
