RCDC_Frame Type: Gravity or Lateral?

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.

Bentley Ram Connection Design

"Hi, this is my first time using RAM Connection Standalone for connection design. In RAM Connection, you can manually input loads and choose load cases according to the code. However, I have a full structural model in STAAD.Pro from which I can extract support reactions.

Instead of the long process of inputting primary loads (DL, LL, WL, EQ) into RAM Connection and letting the software simulate the most critical conditions, would it be safe to simply use the maximum reactions from the supports and combine them into one design? Specifically, I would take the maximum positive and negative reactions from the X, Y, and Z directions, regardless of which support they came from. Regarding the load type, I would use 'Dead Load' (DL) by default and skip load cases in RAM Connection, since the forces I am importing are already the maximum factored loads from the governing combinations in STAAD.Pro."
