Immediate Seismic Resilience of a Controlled Cable-Stayed Bridge

Resilience issues have multidisciplinary relevance and, in recent years, attracted the interest of the scientific community. Within civil engineering sciences, resilience has been often recognized as an attribute of structures with respect to the outcomes of extreme events. Control systems that can adapt to different loading levels can be exploited when structural conditions change due to local failures to offer a contribution to structural resilience. The innovative aspect is related to how the devices features are changed in real time to improve the loss of functionality function, which is at the base of resilience. When the parameters change occurs in real time, on line with the occurrence of a local failure, the concept has been formerly presented in the existing literature as “immediate resilience”, along with a new measure index of resilience. Immediate resilience theory is herein reviewed and underlined with reference to a new seismic case study, coming from a control benchmark, for which strategies for recovering after a damaging event the initial performance of the controlled bridge are presented.
