Abstract:The steel roof of Tsingdao international sailboat center for 2008 Olympic Games is so special that its shape is of an arc, which is made up of Hbeam and pipe column.
It is introduced how to analyze integral stability performance of the structure applying eigenvalue buckling analysis and all course tracing by nonlinear finite elements. According to the results,the roofing structure is arranged, which is composed of the whole spatial structure system.
Keywords:steel roof; stability analysis; eigenvalue buckling analysis; all course tracing; nonlinear finite element
