Abstract

Passively controlled structural systems may be exhibiting scarce capability in resisting dynamic solicitations under adverse special or unexpected conditions. Improvements of the overall performance of the passive system may be obtained when introducing supplemental corrective control actions, possibly coupling different technologic solutions and moving to mixed systems. In the paper the performance of a base isolation system is increased by embedding in the control layout an additional passive/active device, commanded by a newly designed control algorithm. The main novelty lays in the overall control system, which is regarded and completely newly designed as a whole rather than coupling already existing separated control systems, which are usually adopted and forced to comply with each other, thus realizing full complementarity. The proposed approach is aimed at further improving the reliability of the control system, ensuring its functionality even when unexpected adverse conditions occur, causing ineffectiveness of the main system.
