摘要: 中國華潤大廈建筑高度 392. 5m,結構體系采用鋼結構密柱框架 ̄核心筒的體系,由于圓形的平面和春筍的造型,大樓在 10 年一遇的風荷載下具有較為顯著的動力響應。 對結構進行了抗風的減振設計,采用黏滯阻尼器,并且對阻尼器的設置位置、結構形式、計算參數等進行了優(yōu)化,取得了很好的減振效果。 提出了對阻尼器及其連接的全程設計指標要求、技術性能要求,并進行試驗測試和實施考慮等,保證阻尼器的安裝和順利工作。 分析結果表明:設置了黏滯阻尼器之后大樓的振動加速度得到有效地控制,可以滿足提高舒適度標準的設計要求。

Abstract: The height of China Resources Building is 392. 5 meters with structural system of steel close column frame ̄coretube system. Due to the circular plan and the shape of bamboo shoot, the building has a relatively significant dynamicresponse under the 10 ̄year wind load. Wind ̄induced vibration was designed. The viscous damper was adopted, and theoptimization of location for dampers, structural supporting form, analysis parameters and else were optimized. A goodvibration reduction effect has been achieved. The design measure requirements, technical performance requirements of thedampers, experimental testing and implementation considerations were put forward to ensure the installation and smoothoperation of the dampers. Analysis results show that after viscous dampers adoption, the wind induced vibration of structurecan 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
