ABSTRACT
This work extends some recently obtained results on the identification of base isolation systems from earthquake response records. The identification is carried out by means of the Covariance Matrix Adaptation - Evolution Strategy (CMA-ES). By extending the number of iterations in each run and the number of runs it is shown that the obtained results have engineering significance. The design of a fictitious problem on the basis of a real seismic isolation system has allowed for the evaluation of the error on the individual system parameters. Some information on the completeness of the data used for the identification has also been provided. The work is concluded by the description of some open problems that the authors are facing and are determined to solve using the recent advances in computer science and technology.
