【摘要】 针对常州东经120主题公园景观塔(摩天轮)这一特殊的高耸结构为对象,研究调频质量阻尼器(TMD)系统风振响应控制效果。根据结构的自振特性,考虑TMD系统结构质量比为0.010、0.015和0.020时的情况进行设计,综合考虑工程使用了质量比为0.010的16个TMD系统,SPA2000三维模型分析表明工程设计的TMD系统在风作用下可以有效地发挥减振作用,在风速26.8和13 m/s的作用下结构顶点加速度的减振率分别可以达到30%和34%。更多还原

【Abstract】 Wind-induced response control effect of the tuned mass damper(TMD) system on a landscape tower in Changzhou E120 theme park was studied.According to the vibration characteristics of the structure,it was designed with 0.010,0.015 and 0.020,of mass ratio of TMD system and the structure simultaneity 16 TMD system was considered,and its total mass ratio was more than 0.010.The computing results of SAP2000 showed that the TMD system of the project in wind had the damping effect.Under conditions the cases of 26.8 and 13 m/s of the wind,the peak accelerations were reduced by 30% and 34%.更多还原
