大连市中心体育馆巨型网格弦支穹顶设计分析
|
摘要
大连市中心体育馆屋盖选用巨型网格弦支穹顶结构,尚属国内较为新颖的结构体系。为此,利用ANSYS及SAP2000软件开展结构体系的静力分析,采用非线性动力时程分析法和反应谱法开展抗震性能研究,并进行了风洞试验研究及风振响应分析,进一步开展全过程施工模拟。巨型网格弦支穹顶结构用钢量经济、承载力较高、抗震性能优越、抗连续性倒塌能力强,适合于在大跨度建筑中推广和应用。
The structure of giant grid suspend-dome which is used in Dalian Centre Gymnasium is a kind of relatively new structural system at home.Therefore,this paper uses ANSYS and SAP 2000to carry out the static analysis for this structural system,and adopts nonlinear dynamic history analysis method and response spectrum method to study seismic behavior of the structure.Meanwhile the wind tunnel test and wind-induced dynamic response are conducted for this structure.In addition,the whole-course of the construction of the giant grid suspenddome is simulated.From this paper we can draw the conclusions:the giant grid suspend-dome has the lower steel volume,the higher critical load,the excellent seismic behavior,and strong ability of resisting progressive collapses.It is suitable for the promotion and application in large span buildings.
