摘要
福州海峡国际会展中心的建筑平面呈椭圆形,长轴方向最大尺寸约468m,短轴方向最大尺寸约130m。主体结构采用钢筋混凝土框架结构,屋盖采用大跨空间钢结构,连廊最大跨度30m,对其进行人流通行时的震动控制研究,提出合理的震动控制方案。采用可调频TMD阻尼器,结构节点位移及震动均明显降低,有效减小结构在人流通行过程中的震动反应,提高结构的舒适度。棋盘井职工活动中心的建筑平面呈3个相切的圆形平面,直径均为72m,中间采用大跨度钢结构连廊相互连接,连廊部分跨度最大跨度14m。为满足设计的会议室使用功能要求,采用可调频TMD阻尼器,调节震动频率,满足结构舒适度要求,提高结构的安全性、舒适度及经济性。
The building plane of Fuzhou Strait International Convention and Exhibition Center is regular ellipse and the long axis and short axis are 468m and 130m,respectively.The major structural form is reinforced concrete frame,and the roof is large span spatial steel structure.In order to enhance the capacity to resist seismic and wind load,the vibration control under wind and earthquake,has been studied and meanwhile the reasonable vibration control plan has been decided.After adopting viscous dampers and universal rotation bearing,both the displacement of structural joint and member stress decrease significantly;moreover the seismic response of structure has been decreased.Finally the design plan has been modified and optimized following the analysis results.Its safety,reliability and economy has been improved.
