摘  要:惯容器是一种两端点加速度相关型控制元件,具有表观质量放大、耗能增效等特性,可更加高效、经济地进行结构振动控制,将惯容器表观质量增大的特性拓展到调谐减震装置中可实现轻量化振动控制。为研究高层结构上附加旋转惯质双调谐质量阻尼器(rotating inertia dual-tuned mass damper,RIDTMD)的轻量化振动控制效果,采用柔度法求逆的方法获得等效简化模型;通过结构模态分析、时程分析验证了等效模型的可靠性;建立附加RIDTMD多自由度结构的力学模型与运动方程;采取H_(2)优化和给定质量、阻尼参数的取值区间来确定RIDTMD的参数。在一个51层的框架核心筒结构上设计了RIDTMD,分析其在地震激励下的楼层位移、加速度和层间位移角等结构响应,频域与时程分析结果看,以调谐质量阻尼器(tuned mass damper,TMD)控制效果为目标的H_(2)优化设计可以使RIDTMD有着与TMD类似的振动控制效果,与无控结构相比,顶层峰值位移、均方根位移最大可分别降低18.0、32.9%,且RIDTMD的调谐质量比TMD减少30.0%。Inerters are a type of two-end acceleration related control components,they have characteristics of apparent mass amplification,energy dissipation and efficiency improvement.They can be used for more efficient and economical structural vibration control.Extending feature of apparent mass amplification of inerter to tuned seismic reduction device can realize lightweight vibration control.Here,to study the lightweight vibration control effect of additional rotating inertia dual-tuned mass damper(RIDTMD)on high-rise structures,an equivalent simplified model was obtained by using the method of inverse-solving with flexibility method.The reliability of the equivalent model was verified with structural modal analysis and time history analysis.Mechanical model and dynamic equation for a multi-DOF structure with additional RIDTMD were established.The parameters of RIDTMD were determined by using H_(2) optimization and given value intervals for mass and damping parameters.A RIDTMD was designed on a 51-story framework core tube structure,and structural responses of floor displacement,acceleration and inter-story drift angle under seismic excitation were analyzed.Frequency domain and time history analysis results showed that H_(2) optimization design taking tuned mass damper(TMD)control effect as the objective can make RIDTMD have similar vibration control effect as TMD’s;compared with uncontrolled structure,peak displacement and RMS displacement of top story can be reduced by 18%and 32.9%respectively;tuning mass of RIDTMD can be reduced by 30%compared to TMD’s.
