摘要：
An efficient approach to the analysis of non-stationary random responses of structures subjected to evolutionary random excitation is proposed, The random excitation is first transformed into a pseudo excitation to generate deterministic equations of motion, which are then solved by means of a modified high precision direct integration method. Numerical examples demonstrate the high precision and efficiency of this approach. (C) 1997 Elsevier Science Ltd.
