［摘要］针对某钢结构登机桥的人致振动减振控制，采用结构减振控制理论，选取调频质量阻尼器(TMD)对结构进行人群荷载作用下的振动控制与舒适度设计。采用有限元分析软件MIDAS/Gen建立结构三维分析模型，对多种人群荷载工况输入下减振前后楼盖结构的动力响应进行时程分析；对大跨度楼盖动力特性与安装TMD前后的人群荷载下最大加速度响应进行现场振动测试，对减振前后结构的实测加速度响应进行对比分析。结果表明，采用TMD减振方案并根据实测结构动力特性调整其刚度可以使结构满足人群荷载作用下的舒适度要求，TMD起到了良好的减振效果。

Abstract:In order to control the human-induced vibration of a steel structure terminal aerobridge, structural vibration control theory was adopted and tuned mass damper (TMD) device was used to control vibration under human loading and carry out comfort design. The three-dimensional analysis model of the structure was developed based on the finite element analysis software MIDAS/Gen, and time-history analyses were carried out on dynamic responses of floor structures with different human loading working condition inputs before and after vibration control. Field vibration tests were conducted on the dynamic properties of large-span floor and the maximum acceleration responses under human loading before and after TMD installation. The acceleration responses of the structure before and after vibration control were compared and analyzed. Results show that the structure meets comfort requirements under the human loading when TMD vibration control scheme is adopted and TMD stiffness is adjusted according to the actual measured structural dynamic properties.TMD has good vibration control effect.
