Folded Sheet

hello, I can not get the key moments of the structure in a folded sheet, when I do verification on paper does not match the model . I also did a file to compare moments and deformations in a vertical element 1m x 0.1m , one is a mesh and the other is one beam, the deformations coincide, but not the moments , so I think the key moments in the folded sheet for this not verified. as I can fix it?

Thank you

 Patricio
