| Abstract: | Aimed at the buckling of a reticulated shell on the top of the dish gas holder,which was caused by negative pressure,a geometrically nonlinear finite element method is adopted to analyse the stability of the ribbed shell that is usually used for the top of a dish gas holder.A formula of elastic critical pressure of the general buckling and calculation method of member effective length for the ribbed shells are attained. |
