RCDC_Frame Type: Gravity or Lateral?
Basically when i model in Staad pro, I separate the substructure and the superstructure. Im trying to design the substructure via Staad Pro's advanced concrete design which is RCDC and it is my first time using it. I have already transferred the resultant forces from my superstructure to my substructure and ran the appropriate analysis options.
In RCDC i found out that it assigned my structure as gravity frame type. In RCDC it can be either gravity or lateral frame type. Why was mine assigned as gravity frame and what does it mean if it is gravity or lateral frame type? Could the reason to that is because in my staad model the columns are not connected to each other via beams?
Also, can someone explain to me what links and ductile links are? because i observed that when my frame type is gravity, RCDC doesn't give off information under links, only ductile links. But, when i changed it to lateral frame type information appears under the links column.
Under lateral frame type there is information under the Links Column
Under gravity frame type there is no information under the Links Column
Substructure model. This serves as the pedestal for my steel structure in my superstructure model.
