摘　　要：以深圳恒裕金融中心B塔项目为例,通过对比结构顶点加速度、顶点位移、层间位移角、倾覆力矩的变化及附加阻尼比,验证了液体黏滞阻尼器在超高层建筑抗风中的明显减振效果。本文对目前建筑结构动力参数实测的方法以及测试设备进行了解释,同时,也介绍了对恒裕中心在设置阻尼器前后的结构基频、阻尼比、风振舒适度的现场测试情况。通过测试,验证了设置阻尼器可以有效降低结构在风振下的振动,提高结构的舒适度水平。测试结果受到外部因素影响其准确性虽然不足,但阻尼比和顶层加速度降低的趋势是确定的。这次测试也是世界上首次对设置了液体粘滞阻尼器结构进行的实体建筑的动力参数测试。Taking the Tower B project of Shenzhen Hengyu Financial Center as an example,the obvious vibration absorption effect of liquid viscous dampers in wind resistance of ultra-high-rise buildings by comparing the variation of structural vertex acceleration,vertex displacement,interlayer displacement angle,overturning torque and additional damping ratio is verified.The current method of measuring the dynamic parameters of the building structure and the test equipment are explained.At the same time,the on-site testing of the base frequency,damping ratio and wind vibration comfort of Hengyu Center before and after the damper is set up is also introduced.Through the test,it is verified that setting a damper can effectively reduce the vibration of the structure under wind vibration and improve the comfort level of the structure.
