（北京市建筑設(shè)計(jì)研究院有限公司， 北京 100045）［摘要］深圳寶安國(guó)際機(jī)場(chǎng)T3航站樓下部主體結(jié)構(gòu)為鋼筋混凝土框架結(jié)構(gòu)，屋頂采用自由曲面的鋼結(jié)構(gòu)，由主樓和呈十字交叉的指廊組成。屋頂縱向較長(zhǎng)，采用了固定鉸支座和彈簧支座結(jié)合的形式。為限制地震作用下結(jié)構(gòu)沿長(zhǎng)向的位移，在加強(qiáng)桁架支座附近安置了速度相關(guān)型黏滯阻尼器。重點(diǎn)介紹項(xiàng)目采用阻尼器的參數(shù)設(shè)置方法,該方法能夠快速合理地確定阻尼器參數(shù)，可為類(lèi)似工程設(shè)計(jì)提供參考。［關(guān)鍵詞］航站樓; 消能減震; 阻尼器; 超長(zhǎng)結(jié)構(gòu); 附加阻尼比中圖分類(lèi)號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)18-0087-04
Study on energy dissipation of Shenzhen Bao′an International Airport T3Yang Yuchen, Zhu Zhongyi, Qin Kai, Zhang Lin(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: Shenzhen Bao′an International Airport T3 has lower main structure of reinforced concrete frame structure and free surface steel structure adopted as the roof. It is composed of the main building and criss-cross corridors. The bond form with the fixed hinge bearing and the spring bearing is used in the super-long roof. In order to control the displacement of the structure along the length direction under earthquake action, the speed-dependent viscous dampers are placed near the bearings of the strengthening trusses. The method of setting the damping parameters was introduced in detail. The damping parameters can be determined reasonably and rapidly by this method, providing reference for the similar structural designs.Keywords: terminal; energy dissipation; damper; super-long structure; additional damping ratio
