ABSTRACT

Recent progress in response analysis of inelastic structures under nonstationary random excitation is reviewed. Emphasis is on realistic consideration of the time-varying intensity and frequency content of the excitation, detailed nonlinear response behavior of the structural frame including inelastic hysteresis and deterioration with time, and computational efficiency of the method. The usefulness of the method in practical application is demonstrated by examples of response and safety evaluation of real structural systems under seismic excitations.
