In this paper the analytical formulation of frequency domain analysis is reviewed, under a unifying approach, for deterministic and random dynamic loading. In the random case both stationary and nonstationary excitations are considered. It is shown how, in all cases, a complex linear system must be solved at each frequency step; if the solutions are carried on independently, the solution cost grows almost linearly with the number of steps. Aiming at a computationally more efficient approach… CONTINUE READING
