Does anyone know how to enter Story Does anyone know how to enter Story Bagman2524 (Structural) (OP) 12 Sep 18 17:46 Does anyone know how to enter Story Drift as an input value (if it is even possible at all) to STAAD? We have a project with given story drifts and have to design stairs with story drift included. All I know is P/A and Mc/I RE: Does anyone know how to enter Story WARose (Structural) 12 Sep 18 23:14 Not that I am aware of. Checking the manual (Sect. 126.96.36.199), it says: The story drift determination as explained in Section 12.8.6 of the ASCE 7-10 code is not implemented in STAAD. I've seen people amplify load combinations by a calculated factor (to get the seismic drift) and note the combination as doing that.....but I am not aware of any automatic way of doing that in STAAD.
