This symposium will provide a forum to present topics related to structural control, with special emphasis on their effects on the life cycle performance improvement of aging structures.
High-rise structures, such as skyscrapers and wind turbines, are subjected to fatigue critical alternating loads induced especially by wind. In consequences of these dynamic loads, for instance, typical wind turbines can reach usually only a service time of 20 years, which is compared to design, fabrication and installation costs economically inefficient. Critical infrastructures, particularly the transportation structures, are jeopardized also by other dynamic loads, such as operational and traffic loads. Countless highway and railway bridges in both the USA and Europe require for the improvement of fatigue behavior urgent retrofitting measures.
In this context, the symposium covers, but not limited to, passive, active and semi-active structural control strategies using auxiliary damping devices, such as dissipators, tuned mass dampers, tuned liquid column dampers, tuned liquid dampers and other devices based on smart materials.
Furthermore, the symposium will mention the utilization of structural control for the improvement of structural reliability during natural hazards, such as earthquakes.
In this framework, calculation methods, computational simulations, testing methods, such as real-time hybrid simulations (RTHS), and application examples of structural control systems will be the main topics in this symposium.
