ABSTRACT
A research has been carried out providing for the generation of a set of variants of a structural model, resulting from a random distribution of the capacities of all the members, accounting for the uncertainty in member capacity. Simulations of the seismic response of the variants allow to obtain a sample of the response parameters, from which the probability density functions (PDF) of their distribution can be identified and the corresponding fragility curves can be finally drawn. The fragility curves will enter in a performance-based procedure leading to the probabilistic evaluation of the earthquake consequences.
