Mitigation of wind-induced vibrations in high-rise dry-assembled precast concrete residential tower buildings

Dry assembled precast concrete is currently trending for the construction of low- and medium-rise residential buildings, especially in countries requesting high construction volumes in limited time. Recently, dry-assembled precast technology was investigated to be applied for the construction of high-rise buildings, too. This paper analyses the dynamic response of a 100m tall residential tower fully designed and detailed under static loads with a dry-assembled couples frame/wall precast structural system, when subjected to Vortex Induced Vibration (VIV). Within this framework, the efficiency of different distributions of Tuned Mass Dampers (TMDs), from one bulk device positioned at the top to smaller devices distributed along the height of the building, in mitigating the wind-induced dynamic response is investigated through a parametric analysis.
