Summary This study presents a new crosswind mitigation strategy by using negative stiffness damped outrigger (NSDO) system for tall buildings. Using the “assisting motion” feature of negative stiffness, NSDO amplifies the motion of viscous damper resulting in and significant improvement of energy di...
