Identificazione di controventi concentrici nel dominio del tempo

With the aim to explore the efficacy of identification techniques and damage indices, in this paper a numerical example is presented with reference to a concentric braced steel frame designed according to the recent Italian seismic code. The analyses have been performed considering different damage scenarios and adopting the procedures proposed by some of the authors of this paper for identifying the dynamic and physical properties of examined structures. Finally, different damage indices have been used to evaluate the damage of braces.
