摘要：
With the ever increase of the building height, the structural natural frequency becomes more and more closer to the predominant frequency of the strong wind, and therefore the building acceleration induced by wind load become increasingly prominent. The viscous damper is a kind of velocity-dependent damper without additional stiffness, which can reduce the vibration response of the structure under both earthquake and wind. The mathematical model of the optimal geometric parameter of the reverse toggle brace damper system is formulated. The procedure to find the optimal geometric parameter of the reverse toggle brace damper system is also discussed in detail. Besides, a new optimal design method to find the optimal placement, number and damping coefficient of viscous damper systems under the constraint of human comfort performance and additional damping ratio is proposed. A real 250 meter super tall residential building project is employed to illustrate the effectiveness and applicability of the proposed optimal wind-induced vibration attenuation design of viscous damper systems for super tall structures. © 2018, Nanjing Univ. of Aeronautics an Astronautics.
