Abstract

The fundamental equations of motion of soil-hysteretic building structural systems under earthquake-like random excitation are derived. Taking into account the non-stationary and non-white spectral characteristics of the excitation, the ordinary differential equations are derived for the covariance responses. Based on these responses, a new approach to estimation of the maximum ductility factor response is developed, and the probability of structural safety is examined. Numerical examples are presented and the accuracy of the proposed approach is demonstrated. The possible substitution of non-stationary spectral characteristics of the excitation for stationary ones is discussed through the examination of the response characteristics.
