Kris - I changed to space eval and yes...I had some global z reactions from the local Y member loads. I'm not sure why as it seems I am applying the load only in the X-Y plane.
More info on the model...
This is an arched frame roof with with straight side walls.
The structure has a dual pipe inner and outer chord members (I input combined shape prismatic member properties).
The arch portion is modeled with curved members.
Curved members have the local Y member load since that seems to be the only way to apply them (wind pressure). This is causing the out of plane loading.
I did not beta any members, so as far as I can tell the local Y axis of each curved member IS in the x-y plane. With loads in model view this appears to be true.
Any other thoughts?
