Rotational inertiaacceleration is NOTcalculated neededindependently forfrom rotational acceleration. Ainertia. This is done by applying, at the global origin, a unit rotation is applied about the given axis atconsidered thefor globalrotational-acceleration origin. Incomputation. 

While applying a rotational acceleration load during time-history casesanalysis, youusers canmay specify a coordinate system and an angle (about Z), and the rotationalfrom the vertical Z-axis.

forTranslational rotational inertiaacceleration, if any. Atat any point in thea structure, the translational acceleration is given by the cross product of the position vector from(relative theto origin of rotation) and the acceleration vector. TheResultant force is then the negative of the product of this translational acceleration value timesand the translational mass. will be the force. TheFor example, RY acceleration generateswould generate MY, FX, and FZ values. 
This is basic mechanics, the conjugate to summing moments at a point from moments and forces distributed throughout the structure.
