Where the calculated fundamental period exceeds CuTa in a given direction, CuTa is used in lieu of T in that direction. Where the combined response for the modal base shear (Vt) is less than 100% of the calculated base shear (V) using the equivalent lateral force procedure, the forces shall be is multiplied by V∕Vt
12.9.1.4.2 Scaling of Drifts
Where the combined response for the modal base shear (Vt) is less than CsW, and where Cs is determined with Eq. (12.8-6), drifts is are multiplied by CsW∕Vt.
