θmax

θ should not exceed the lesser of θmax, given by the equation, as the structure is potentially unsafe and should be redesigned.

θmax  = 0.5βCd≤0.25

Cd

Deflection amplification factor in Table 12.2-1

β

Ratio of shear demand to design shear capacity for the story between levels x and x-1 (taken conservatively as 1.0, but not less than 1.25/Ω0)
