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 …

Recently, damped outrigger structures have shown great potentials in suppressing
vibrations of tall buildings subjected to seismic and wind excitations. To gain insight into the …

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 …

This study examines the ability of damping devices placed between outrigger trusses and
perimeter columns to mitigate dynamic vibrations in a tall building structure. The …

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 …

Outriggers have been proven to be an efficient system to reduce the dynamic responses of
core-tube type high-rise buildings by utilizing the axial stiffness of the peripheral columns …

Tall buildings suffer from low inherent damping and high flexibility. Therefore, a core‐
outrigger system is often used to stiffen such buildings. A modified form, known as the …
