The synthesis of optimal controllers for vibrational protection of large-scale structures with multiple actuation devices and partial state information is a challenging problem. In this paper, we present a design strategy that allows computing this kind of controllers by using standard linear matrix inequality optimization tools. To illustrate the main elements of the new approach, a five-story structure equipped with two interstory actuation devices and subjected to a seismic disturbance is considered. For this control setup, three different controllers are designed: an ideal state-feedback H ∞ controller with full access to the complete state information and two static output-feedback H ∞ controllers with restricted neighbouring state information. To assess the performance of the proposed controllers, the corresponding frequency responses are investigated and a proper set of numerical simulations are conducted, using the full scale North-South El Centro 1940 seismic record as ground acceleration input. The obtained results indicate that, despite the severe information constraints, the proposed static output-feedback controllers attain a level of seismic protection that is very similar to that achieved by the ideal state-feedback controller with complete state information.

Abstract-An innovative floor anchorage system is being developed that reduces inertial forces in building structures during major earthquakes. This goal is accomplished by providing the anchorage a design strength lower than that required to transmit the elastic diaphragm forces. Instead, at a predefined "cut-off" load, the anchorage deforms ductily, transforming the diaphragm seismic demands into relative displacement of the floor system with respect to the primary vertical elements of the lateral force resisting system. The floor anchorage system has the potential to reduce the diaphragm inertial forces, thereby lowering floor accelerations and reducing seismic demands on the lateral force resisting system, resulting in less damage to the structure, non-structural elements and building contents. This paper presents preliminary analytical findings on the performance of the floor anchorage system, focusing on the sensitivity of system properties on structural seismic response. The analytical study shows significant seismic response reduction in the proposed floor anchorage system. Index Terms-Seismic resistance system, floor anchorage system, structural damage, structural seismic response.
