Translational acceleration loads
Acceleration loads are used to simulate the ground motion of a time-history acceleration record. CSI Software assumes complete fixity for all supports, then automatically computes acceleration loads at each node and element. Translational-acceleration loads are taken as the negative of the product of assembled joint mass and input acceleration.

Rotational acceleration loads
Rotational acceleration is calculated independently from rotational inertia. This is done by applying, at the global origin, a unit rotation about the axis considered for rotational-acceleration computation.
