Hello, I would like to have some information about the exact way ETABS calculates the sory drifts. For example if a point is selected in deformed shape of reponse spectrum load case, ETABS displaces both displacements and drifts. What I can't understand is why the difference between the displacements in two adjacents floors divided by the floor height, is not equal to the value of the story drift calculated by ETABS.
