text: For a structure where centers of mass align, the story drift is computed based on the center of mass displacements.
text: For a structure where centers of mass do not align (more than 5% eccentricity between the center of mass), the story drift may be computed based on a vertical projection of the center of mass of the upper story to the lower story, and relative displacement of the projected point used.
text: For structures in Seismic Category C, D, E, or F with horizontal irregularity 1a or 1b, the story drift is computed based on the largest difference of aligned points at the edge of the structure.
