Good Morning, I need some help about my girder bridge example.
I think it’s all good about the assemble model part, with correct collaboration beetween beams and shell, but I can’t understand the results about shell forces.
When I analyze the upper stage of the shell, as the deformation, there is compression stress, and obviously, the lower stage had tension stress. So, Why the shell forces component, gave me a lot of Normal Forces value (KN/m) > 0 (Tensile stress) larger in number and entity then the compression one?
In addition, if I flatten the normal forces value in output of the component, I obtain larger value in entity then the same not flatten. Why it happen? What’s the value I’ve to consider for my analysis?
Thank you in advance.
