| Abstract: | It is very meaningful to develope numerical method for shell structure. In order to solve the simplified equations of the rectangular base shallow shell with the simply edges, we adopt the 3rd and the 5th B-spline functions as basic function. and use three methods seperately: the Collocation Method, the Least Squares-Collocation Method and Galerkin-Collocation Method.to get its solution. It is indicated that the simplified equations are reliable and the Weighted Residual Method is simple,effective and worth studing further. |
