摘要
In view of hybrid vibration control of high-rise building structures in horizontal and vertical earthquake actions, the vibration reduction effects of tuned mass damper (TMD) system, isolated structure system and hybrid control system of both on structural vibration response in horizontal and vertical earthquake action are studied. A typical 20-story steel structure model is chosen while the finite element model of the structure with TMD and isolation layer is established with the use of ANSYS software. The vibration responses of the structure in horizontal earthquake actions and horizontal plus vertical earthquake actions are thereafter compared. The results show that there is no obvious change in the horizontal vibration response, while vertically the vibration reduction index in the controlled state increases compared with that in the uncontrolled state, particularly in the story isolation structure. The research results can provide reference for the design of high-rise isolated structures in high intensity earthquake zones. ? 2022 Xi'an Jiaotong University.
