<p style="box-sizing: border-box; margin: 0px 0px 10px;"><span style="background-color: rgba(255, 255, 255, 0);">High performance control systems (HPCS), including semi-active, active and hybrid supplemental damping systems, are effective solutions to increase
structural performance versus multi-hazard excitations. However, the implementation of HPCS within structural systems is still in its infancy, because of the complexity in designing a robust closed-loop control system that can ensure reliable and high mitigation
performance. In this seminar, these closed-loop challenges impeding the implementation of HPCS are introduced, with a particular attention to multi-hazards applications. Two devices for HPCS are presented as possible solutions, including a semi-active structural
cladding connection and a variable rotary friction device, both developed in collaboration with Lehigh University. Lastly, an intelligent controller that has the particularity to adapt in real-time to different hazard dynamics is briefly discussed, and its
performance demonstrated.</span></p>
