摘  要:以地震多发区超高塔楼为工程背景,综合黏滞减振系统的布置位置、多种变形放大连接装置、黏滞阻尼参数等关键参数进行了风振和地震双激励下的黏滞减振系统选型分析,并以一幢396 m高的超高综合塔楼为例对风振和地震双激励下黏滞阻尼减振系统设计进行了研究。研究结果表明,黏滞阻尼减振系统对于不同模态响应均有一定的控制作用,可以有效提升风振和地震情况下结构的舒适度、刚度和强度,合理的阻尼器布置位置、变形放大装置和参数选取可以获得更加高效的减振效率。This paper is based on the engineering background of super-tall towers in earthquake prone areas,comprehensively arranges the position,various deformation amplification devices,viscous damping parameters and other key contents to carry out the selection and analysis of viscous damping systems under wind and earthquake double excitation.Taking a 396 m super-tall tower as an example,the design of viscous damping systems under wind and earthquake double excitation is studied.Research has shown that viscous damping vibration reduction systems have a certain control effect on different modal responses,which can effectively improve the comfort,stiffness,and strength performance of structures under wind and earthquake conditions.Reasonable placement of dampers,deformation amplification devices,and parameter selection can achieve more efficient vibration reduction efficiency.
