As buildings increase in height and slenderness they become increasingly sensitive to wind and seismic dynamic vibrations. Currently, when engineers are faced with vibration perception problems, they must either, reduce the height of the building, increase the lateral stiffness of the structural system, or use specialized vibration absorbers such as Tuned Mass Dampers (TMD). A new damper concept for high-rise buildings has been developed through collaboration with Halcrow Yolles of Toronto, which mitigates dynamic wind and seismic vibrations. The new damper configuration can be directly incorporated into existing structural configurations such as coupled structural wall buildings. This new configuration is non-obtrusive and will not affect usable space of the building.
