| Abstract: | In this paper, the equation of the curved surface of the shell structure with combined paraboloids is firstly established by means of the step function on the inclined coordinates. Then the computational formulas for the nonlinear analysis for the traditional combined paraboloid roof is derived from the nonlinear theory of shell, and the Galerkin method. |

| Keywords: | : combined shallow shell with different paraboloid surfaces geometrically nonlinear analysis |
