obtained fragility curves allow to study how the seismic fragility of a given structural class changes over the time (i.e., with the construction age) and going from low to high rise buildings. Further studies will be about the introduction of uncertainties (such as related to the ground motion intensity) in the adopted approach, to account for their effects on the shape curves. Secondly, also the efficiency of several IMs (i.e., peak ground velocity, spectral acceleration at the building’s period, the averaged spectral acceleration, …) in addition to PGA, will be investigated.
