This paper presents the development of the outrigger structural system from the
conventional outrigger to damped outrigger concepts. Outrigger structural system …

It is known that the performance of traditional passive tuned mass dampers (TMDs) is highly
sensitive to vibration frequency. The fundamental frequency of existing tall buildings may …

By introducing negative stiffness devices, this study further improves the maximum
achievable damping ratio of conventional damped outrigger (CDO) structures with flexible …

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 …

In this paper, the seismic performance of conventional damped outrigger (CDO) is improved
by incorporating negative stiffness (NS) in parallel with the viscous damper. The applied …

This paper proposes outrigger tuned inertial mass electromagnetic transducer (TIMET)
systems for high-rise buildings subject to long period earthquake excitations. The proposed …

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 …

High-rise buildings have attracted much attention with the continuing growth of world
population and increasing urbanization. As buildings become taller, suppressing excessive …

The damped outrigger system, an improvement of the conventional outrigger system, can
contribute to better vibration control in high-rise buildings through proper supplemental …

This study proposes complex rotational stiffness for modeling multiple damped outriggers in
a tall building. The complex rotational stiffness considers interaction between peripheral …
