The bar type is the set of the parameters you want to use in the design modules of Robot. It is irrelevant for static calculations of the model itself.
Replace the top and bottom arch with lines from one bar intersection to another. Save the file as a dxf. Open it in Robot.
Try to replace the arches in AutoCAD with lines from node to node.
