常州东经120主题公园景观塔TMD风振控制分析
TMD control for wind induced vibration of Changzhou E120 theme park landscape tower
摘要
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%.关键词
