This paper proposes an integrated damping system that aims at providing relatively high damping levels through the mobilization of a proportion of the structure's own mass. This offers significantly higher mass levels and, consequently, considerably more damping compared to conventional tuned mass dampers. Fluid viscous dampers are used to control accelerations in parallel with springs to resist the static loads applied to the moving mass. The advantages of employing relatively large mass levels in achieving considerable damping and reducing sensitivity to tuning are first analyzed using an idealized two degree of freedom structural representation. This is then followed by a description of the proposed “integrated damping system,” which is illustrated through a case study of a 250‐m tall building. The benefits of the proposed damping system are demonstrated through several numerical parametric assessments, as well as a selected suite of earthquake records. For the adopted case study, it is shown that, besides reducing the level of perceivable accelerations, the use of the suggested arrangement can offer an equivalent damping exceeding 50% of the critical damping, resulting in more than 40% reduction in the wind loads as well as over 60% reduction in displacement and acceleration response under seismic excitations.

高层建筑的集成阻尼系统

本文提出了一种集成的阻尼系统，旨在通过动员一定比例的结构自身质量来提供相对较高的阻尼水平。与传统的调谐质量阻尼器相比，它提供了更高的质量水平，因此，阻尼更大。流体粘性阻尼器用于控制与弹簧平行的加速度，以抵抗施加到运动质量上的静态载荷。首先使用理想的两自由度结构表示来分析采用相对较大质量水平以实现相当大的阻尼并降低对调谐的灵敏度的优点。然后，对建议的“集成阻尼系统”进行说明，并通过对250米高的建筑物进行案例研究来说明。通过几个数值参数评估以及一组选定的地震记录，证明了所提出的阻尼系统的优势。对于所采用的案例研究，结果表明，除了降低可感知的加速度水平外，使用建议的布置还可以提供超过临界阻尼的50％的等效阻尼，从而使风荷载的减少超过40％。以及在地震激励下位移和加速度响应降低60％以上。
