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

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

High-rise structures and large-span bridges have low vibration frequencies and low intrinsic
damping and hence are subjected to multimode vibrations under environmental excitation …

Long-span bridges have low vibration frequencies and small intrinsic damping, and hence
are subjected to large-amplitude vibrations, eg, vortex-induced vibrations (VIVs), which …

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 …

Buckling-restrained braces (BRBs) emerged to improve the seismic performance of high-rise
structures as compared to the ordinary diagonal bracing. In this paper, the seismic …

The outrigger system is an effective means of controlling the seismic response of core‐tube
type tall buildings by mobilizing the axial stiffness of the perimeter columns. This study …

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 …

In recent years, various kinds of damped outrigger systems, particularly with the negative
stiffness devices, have been shown to effectively suppress excessive vibration induced by …
