摘　　要： 为了实现小高层结构节能与减震的一体化,本文提出了利用西部地区的屋顶储能集水箱与铅芯橡胶支座作为TMD装置减震的设想。建立了该TMD结构体系的动力分析模型,通过SAP2000有限元软件进行模拟,采用动力时程分析方法对其减震效果进行了分析。结果表明,该TMD控制装置使结构的最大层间位移和最大层间剪力降低了约20%,楼层加速度也有不同程度的降低,因此利用储能集水箱-TMD作为结构的减震控制系统具有一定的可行性和实用性。 In order to make the integration of energy-saving and shock absorption of small high-rise implemented,a newly TMD is proposed which combines the energy storage and water collection tank on building roof in the western and lead rubber bearing as an unity to dissipate energy.In this paper,a dynamic analysis model of the newly TMD is established,and simulated by SAP2000,the shock absorption effect is analyzed by using time history analysis method.The results show that the most drift of each layer and the most floor shear of each layer reduce by about 20％,and the maximum acceleration of each layer also decreases in different degree,therefore using energy storage and water collection tank and lead rubber bearing as TMD has certain feasibility and practicality.
