Authors: Afzal Suleman , Fernando Oliveira , Miguel Botto , Paulo Morais
Abstract: This paper presents the results of a study to evaluate the performance of several control algorithms for a semi-active fluid damper aiming to reduce earthquake induced vibrations. The performance of each algorithm is compared considering a single degree of freedom dynamical model subjected to three alternative input actions: two time series of filtered white noise and a synthesized seismic action. The performance of the system is evaluated by measuring the reduction in relative displacement and acceleration. Comparisons are also made with the passive and active systems. The results demonstrate that semi-active devices can be an option for structural vibration mitigation.
