摘　　要：针对水平和竖向地震作用下高层建筑结构的混合振动控制问题,研究调谐质量阻尼器(tuned mass damper,TMD)体系、隔震结构体系、隔震与TMD混合控制体系3种策略对水平与竖向地震共同作用下结构振动响应的减振效果。选取典型的20层钢结构Benchmark结构模型,利用ANSYS软件建立带有TMD和隔震层结构的有限元模型,比较了结构在水平地震单独作用下与水平和竖向地震共同作用下的振动响应。结果表明,水平方向上的振动响应无明显变化;竖直方向上,有控状态下的减振指标相对于无控状态出现了增大现象,尤其是层间隔震结构增大较为明显。研究成果可为高烈度区高层隔震结构设计提供参考。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.
