Hello Folks, I'm doing a linear buckling analysis of a shear loaded square composite panel.
For distribution of the shear load an isotropic frame is fastened around the edges of the panel. I'm supposed to design the plate as a beam with given length, height and material properties.

My question is that how can i integrate the beam and square composite shear panel?, I created the beam in property module but integrating the two is a problem because beam sections can only be applied to wire features.

I tried creating a square wire feature, assigned section with isotropic material properties and in the instance module i merged the square composite panel and the square wire beam, but the eigne values given and plate deformation were not anywhere close from the experiment values, meaning my method didn't work.

Please Help, I need to design that damn frame!

 
I found out the frame is modelled as a beam, but then the problem now i have is to connect the beams around the four edges of the plate with "pins"
Does anyone know how to connect beams with pins?
