超高层建筑结构组合调谐风振控制系统

为充分利用调谐液体阻尼器（TLCD）的经济性和调谐质量阻尼器（TMD）的高效性，提出一种TLCD与TMD相结合的组合调谐阻尼器（CTD），从理论上说明CTD的合理性，推导其运动方程，引入协同损失因子评价其减振性能，并与TLCD和TMD的减振效果进行对比分析.研究表明：CTD不同参数配置时，协同损失因子不同，可达35%；相同参数配置下，CTD减振效果介于TMD和TLCD之间.综合经济和效率因素，CTD是一种很有竞争力的减振手段，具有广阔的工程应用前景.
To fully utilize the high efficiency of the tuned mass damper (TMD) and the economic advantage of the tuned liquid column damper (TLCD), a combined tuned damper (CTD) was proposed, and the wind induced vibration mitigation effects of super tall buildings with such a combined tuned damper, were investigated. A kinematic equation was derived, which verified the feasibility of CTD theoretically. The collaborative loss coefficient was proposed to evaluate the performance loss due to the direct connection of TMD and TLCD to the structure of CTD. A comparative study was made of the vibration control efficiency of CTD with those of TMD and TLCD. The results show that the CTD with different parameters performs differently in vibration control and leads to different collaborative loss coefficients. The maximum collaborative loss coefficient can be up to 35%. With the same parameters, the vibration control of CTD is between those of TLCD and TMD, which makes CTD a competitive vibration control option
