Abstract
Based on the Newmark time stepping formulas a direct numerical integra tion procedure is developed for the nonstationary response analysis of structures subjected to nonwhite random exitations. The derived formu las for the computation of the nonstationary response variance are rec ursive and easy to implement. The stability of the proposed procedure is discussed. It is shown that the stability conditions are the same a s that for deterministic cases. The example given in this paper shows that the introduced procedure is computationally quite efficient as co mpared to the conventional one. Copyright (C) 1996 Elsevier Science Lt d.
