θ p (KH) = Allowable plastic rotation limit for Controlled Damage performance level [rad]
θ p (DAM) = Allowable plastic rotation limit for Preventing Damage performance level[rad]
TBDY Section 5.8.1.3 as' mentioned, stacked plastic behavior model of the plastic hinges calculated controlled damage (KH) Performance Level plastic rotation limit values for θ p (KH) , Eq. (5.7b) is calculated by.
