Abstract

The structure of large ribbed ring stiffened shallow spherical shell is widely used for roof design of gasholders and oil storage tanks. The FEM of scale shell structure is established and the static performance is analyzed. The grid verification and time steps verification are performed to assure the accuracy of the calculation. The research about static performance shows the yield order of components. The elastic critical load values are obtained from the load-displacement curves of the components. Analysis results can be referred for subsequent model testing and engineering design.
