| Abstract: | In this paper the Von Karman large deflection equations are solved for a shallow shell with a rectangular base and supported at its four corners. The me- thod of mixed weighted residuals is used. Two trial functions are suggested, and then the solution of the problem is obtained by asymptotic method. |

| Keywords: | Von-Karnion large deflection method of mixed weighted residuals asymptotic method |
