摘要:中国华润大厦建筑高度392.5m,结构体系采用钢结构密柱框架-核心筒的体系,由于圆形的平面和春笋的造型,大楼在10年一遇的风荷载下具有较为显著的动力响应。对结构进行了抗风的减振设计,采用黏滞阻尼器,并且对阻尼器的设置位置、结构形式、计算参数等进行了优化,取得了很好的减振效果。提出了对阻尼器及其连接的全程设计指标要求、技术性能要求,并进行试验测试和实施考虑等,保证阻尼器的安装和顺利工作。分析结果表明:设置了黏滞阻尼器之后大楼的振动加速度得到有效地控制,可以满足提高舒适度标准的设计要求。

Abstract: The height of China Resources Building is 392.5 meters with structural system of steel close column frame-core tube system. Due to the circular plan and the shape of bamboo shoot, the building has a relatively significant dynamic response under the 10-year wind load. Wind-induced vibration was designed. The viscous damper was adopted, and the optimization of location for dampers, structural supporting form, analysis parameters and else were optimized. A good vibration reduction effect has been achieved. The design measure requirements, technical performance requirements of the dampers, experimental testing and implementation considerations were put forward to ensure the installation and smooth operation of the dampers. Analysis results show that after viscous dampers adoption, the wind induced vibration of structure can be well controlled, and reach the comfort design requirement.
Keywords: super tall building; vicious damper; wind-induced vibration reduction design; wind-induced vibration comfort; vibration analysis
