河南省广播电视塔风振控制方法研究

摘要
对388 m高河南省广播电视塔进行风振控制,采取在塔楼顶部位置设置悬挂水箱减振器(PTTMD)和在天线段分布设置多点调频弹簧阻尼器(MTSD)的风振控制方法。通过分析该钢结构电视塔在无控制装置、仅设有PTTMD装置、仅设有MTSD装置、同时设有PTTMD和MTSD装置这四种情况下的风振响应,并比较各方法的减振效果,结果表明,设置控制装置可以显著降低结构的风振响应。塔楼处的PTTMD在风振控制中起主导作用,而天线段的MTSD则进一步改善了控制效果,且对天线段的鞭梢效应作用尤为明显。
Pendulous Tanks as Tuned Mass Damper(PTTMD) on observation decks and Multi-Tuned Spring Dampers(MTSD) on the top truss for supporting antennas were suggested to control the wind-induced response of Henan TV tower of 388 m in height.By analyzing the response of four kinds of structures including with none control equipment,only setting PTTMD,only setting MTSD,setting PTTMD and MTSD,control efficiencies under different control strategies were obtained.The results show that the wind-induced response is significantly reduced after setting control equipments.Meanwhile,PTTMD plays a leading role during vibration control process,and MTSD further improve control efficiency especially for decreasing the whipping effect of antennas.
