1. Ask ETABS

2. Do not compare slab resuls and story results.

thanks tony.

Your comments help me to define such a right?

1. center of geometry =  F - Coordinates of the center of gravity of story slab

2. center of mass = G - Coordinates of the center of gravity of story

3. center of rigidity = R - Coordinates of the center of rigidity of the section at the height of the story's center of gravity, considering the columns,walls and core walls.

Please. THansk
