Variation of the class 3 (RC, low ductility) rock-to-soil damage increment as a function of the structure and soil frequency ratio f struct/f soil, and the velocity contrast C, for four different values of PGA (from weak on the left to strong on the right). The color code on the top frames corresponds to the Δ(DI), while the bottom curves correspond to Δ(DI) as a function of f struct/f soil for four values of c indicated by horizontal dashed white lines in top frames
