| 摘 要： | 以某文化中心综合体工程为背景,采用TMD进行结构在不同行人荷载模式作用下的减振控制。利用软件MIDAS Gen建立了其有限元模型。在结构空中连廊上采用多点TMD减振控制系统并针对不同工况计算分析了其减振控制效果。分析表明,当空中连廊基频接近人行频率时,TMD可以减小结构的振动加速度,改善结构的振动舒适度。

| Abstract: | This paper takes a cultural center complex project as the background,and uses TMD to control the vibration of the structure under different pedestrian load modes.The software FIDAS Gen was used to establish its finite element model.A multi-point TMD vibration control system is used on the structural sky corridor,and its vibration control effect is calculated and analyzed for different working conditions.Analysis shows that when the fundamental frequency of the air corridor is close to the pedestrian frequency,TMD can reduce the vibration acceleration of the structure and improve the vibration comfort of the structure. |
