Is it possible to return the nodal displacements for a portion of the diaphragm that is not attached to a "frame" element? I'm wanting to look at diaphragm corner displacements for a torsional irregularity check, but my frames (walls in this case) do not necessarily correspond. I have one corner where my frames don't continue all the way to the roof (so i can't pull nodal displacements at the roof), and another corner where I don't actually have an element.
It would be great if I could assign a node (at each floor) at each corner of the diaphragm to view the drifts as that location.
If the diaphragm is rigid you can get this through process - results - drift at control points. If the diaphragm is semi-rigid you can get nodal displacements for all nodes. Use the report option to "Include Results for all Nodes". Be aware that report can be long, so exporting out the data to excel or SQLite tables may be preferable.
