【摘要】：结合GB 50009—2012《建筑结构荷载规范》中的等效静风荷载计算方法,研究设置主被动可切换的混合调谐质量阻尼器(TMD/ATMD)的规则高层建筑结构的风振分析与实用设计方法。将控制系统的风振控制效果按照风振响应方差相等的原则归结为对受控结构的附加等效阻尼比,推导了控制系统最优参数和附加等效阻尼比的计算公式,给出了惯性质量平均最大行程比、主动控制力和额定功率的简化计算方法;并讨论了主动/被动控制模式的切换准则。最后给出以风振控制Benchmark结构模型为对象的受控结构及混合调谐质量阻尼系统的设计算例。算例分析表明:建议的设计方法可以方便地进行受控结构响应分析和控制系统参数设计;混合调谐质量阻尼器可以有效减小设计等效静风荷载和结构的动力响应。
[Abstract]:Combined with the equivalent static wind load calculation method in GB50009-2012, the wind-induced vibration analysis and practical design method of regular high-rise building structures with active and passive switchable hybrid tuned mass dampers (TMD / ATMDD) are studied.According to the principle of equal variance of wind-induced vibration response, the wind-induced vibration control effect of the control system is reduced to the additional equivalent damping ratio of the controlled structure, and the formulas for calculating the optimal parameters and the additional equivalent damping ratio of the control system are derived.A simplified calculation method for the average maximum stroke ratio of inertial mass, active control force and rated power is given, and the switching criterion of active / passive control mode is discussed.Finally, a design example of a controlled structure and a hybrid tuned mass damping system based on a wind-induced Benchmark structure model is presented.Numerical examples show that the proposed design method can be used to analyze the response of controlled structures and control system parameters conveniently, and the hybrid tuned mass dampers can effectively reduce the equivalent static wind loads and the dynamic responses of the structures.
