（北京市建筑设计研究院有限公司， 北京 100045）［摘要］深圳宝安国际机场T3航站楼下部主体结构为钢筋混凝土框架结构，屋顶采用自由曲面的钢结构，由主楼和呈十字交叉的指廊组成。屋顶纵向较长，采用了固定铰支座和弹簧支座结合的形式。为限制地震作用下结构沿长向的位移，在加强桁架支座附近安置了速度相关型黏滞阻尼器。重点介绍项目采用阻尼器的参数设置方法,该方法能够快速合理地确定阻尼器参数，可为类似工程设计提供参考。［关键词］航站楼; 消能减震; 阻尼器; 超长结构; 附加阻尼比中图分类号：TU318 文献标识码：A 文章编号：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
