While analyzing plate girder bridges, we have to assign multiple connections to a member. For example, if we are to connected a cross bracing from the top flange of one girder to the bottom flange of the opposite one we are having to use offset command. But, there is no provision for these members to intersect. But, in reality we would need an intersection point & get the forces to design the gusset plate. So, this is an issue that needs to be resolved in Staadpro.
