Stability Analysis of Shenzhen Kingkey DameishaHotel Atrium Shell

摘要

Stability analysis in the design of single layer network shell structure is very important,rntherefore, the paper systematically analyses the single layer shell of Shenzhen Kingkey Dameisharnhotel atrium. The beam section is selected by the static calculation results of the structure. Thernstability analysis of the structure is on the base of finite-element theory. The upper limit of bucklingrnload is estimated after eigenvalue buckling analysis. In considering the effects of the initialrndefect 、the geometry nonlinearities and material nonlinearities, the paper analyses the stability ofrnthe structure thus determines the limit load of the structure. The result showed that the critical loadrnobtained by the finite element method considering of geometry nonlinearities and materialrnnonlinearities is more rational for the single layer shell.
