The main objective of this course is to introduce structural engineers to the basic principles of passive supplemental damping and seismic isolation systems and to their implementation into real structures for enhanced seismic protection. An introduction on the basic earthquake engineering principles and energy formulation needed to understand the impact of different supplemental damping and isolation techniques on the performance of structures is first provided. The focus is then set on theoretical and applied knowledge on various supplemental damping and seismic isolation systems that have demonstrated potential at raising the performance of buildings and bridges under earthquake ground motions while keeping construction costs reasonable. The course will cover hysteretic dampers, viscous and visco-elastic dampers, self-centering systems, tuned-mass dampers, elastomeric, lead-rubber, metallic and sliding bearings and will present their physical behaviour, analytical modelling, experimental investigations and practical implementations. Design strategies and methods are also presented for each of the supplemental damping and seismic isolation systems.
