These displacements are acceptable if occurring for a view cycles during the earthquake. However the decay time of these vibrations after the earthquake can be up to 20 minutes as the structures have very low damping capabilities. These vibrations may induce low cycle fatigue resulting in cracking effects within the structure. To overcome this problem damping must be added to the structure. In the past this was mainly achieved by diagonal bracing systems with hydraulic dampers, what often results – depending on the project and the seismic impact strength – in uneconomical solutions. A more economic approach to reduce only the vibration decay times is the application of Tuned Mass Damper systems. The aim of this paper is to introduce and describe the design and realization of two large TMD systems for high rise structures with their seismic function benefits: - SOCAR Tower in Baku/Azerbaijan is 200m tall and has a 450t mass double pendulum type TMD with passive damping, and - Danube City (DC) Tower in Vienna/Austria is 220m tall and has a 300t mass single pendulum type with semi-active damping, which is adopting in real time its damping capability. Both TMD systems have in addition redundant end stopper devices to avoid uncontrolled seismic displacements of the huge TMD mass blocks.
