Soil-structure interaction has been recently accounted for by the authors of this work. One of these factors was investigated for a single elastoplastic structure with a flexible foundation excited by vertically propagating shear waves. The concepts for fixed-base yielding systems were extended to account for soil–structure interaction by using the simplified reference model and a nonlinear replacement oscillator proposed by the writers. This work is focused on a simplified procedure for practical damage analysis of structures considering the soil-structure interaction effects. A damage model based on maximum displacement and dissipated energy under monotonic loading is adopted, with the effects of cyclic load reversals being estimated by using a modified Park-Ang index. To simplify the consideration of the soil-structure interaction effects, an equivalent fixed-base oscillator with the same yield strength and energy dissipation capacity as the actual flexible-base structure is applied. Numerical results are presented in terms of dimensionless parameters for their general application, using a set of appropriate earthquake motions to ensure generality of conclusions. The significance of soil-structure interaction in the structural performance is elucidated and the adequacy of the approach proposed is examined
