AoA Members,
I am trying to check the building stability against overturning.
The building consist of 6 story commercial floors(having dimensions as 198ft x 169ft) and a tower consisting of 21story(having dimensions of 152ft x124ft) . The raft under the tower is 72" and 48" under adjacent commercial floors.
I have few queries regarding calculating overturning moment and resisting moment.
1) Will the overturning moment be base shear x Total tower height or summation of (story shear of individual story x Elevation of each story from base).
2) How the resisting moment will be calculated?
