I am not getting this statement , that how to check torsional irregularity . Please Help .
"Torsional irregularity shall be considered to exist when the maximum story drift, computed including accidental
torsion, at one end of the structure transverse to an axis is more than 1.2 times the average of the story drifts of the
two ends of the structure. "
As beam Moment of inertia is 0.35 as per ACI code . if we taking it 35% then where is rest of 65% going ? Kindly give me concept of it , Similarly in Column we are taking it 70% what about remaining 30% ?
