In RAM Frame, are the story displacements in the story displacement report all relative to the ground floor or are they relative to the floor below them? Thanks.
The story displacements are measured relative to the undisplaced shape at each level. They are not drifts and measured relative to the floor below. If you are interested in Story Drifts, use RAM Frame Analysis - Process - Results - Drift. This report will show total displacement, story drift (displacement relative to floor below), and drift ratio (story drift/story height).
