| Abstract: | The global buckling stability of the single-layer shell with shell shape which located in Tianjin Yujiapu is fully analyzed.First linear stability analysis is adopted to estimate the upper limit of the buckling load.Then nonlinear stability character of the shell under varieties of load combination,including the effect of geometry nonlinear and the initial imperfection,is analyzed by nonlinear finite element method.Finally the desirable result is acquired. |
