Definition of the damage index based on the damage state and displacements thresholds of Lagomarsino and Giovinazzi (2006). The black line is the capacity curve; the multi-colored piecewise linear line corresponds to the new defined damage index. d y is the yield displacement (m) and d u is the ultimate displacement (m).
