Numerical simulations and experimental tests were performed in order to evaluate the performance of the system
with each strategy. Several input ground motions were considered: Type 1 & 2 accelerograms for the Portuguese
territory [17] and recorded ground motions [18]. Before laboratory experiments were carried out, numerical
simulations were performed using the identified model and the specific semi-active control strategy to identify the
best controller parameters. The minimum of mean peak mass ms acceleration
