Effect of the soil-structure interaction on performance assessment of the energy-based cumulative damage index in concrete reinforced frames

In most of the conventional design methods, the soil beneath the structure is assumed to be rigid, but this assumption is not true in reality. Up to now, many studies have been performed concerning the interaction effect on the structure response but the effect of this phenomenon on the structure da...
