This paper deals with the multi-hazard vibration reduction of high-rise buildings in resisting earthquakes and winds, emphasizing on the optimization of supplemental negative stiffness damped outrigger (NSDO) system. Since the risks of wind and earthquake are both inevitable, the competing relations...
