| Abstract: | A new method for analyzing plate frame and stiffened plate structure is presented by combining the weighted residual method with the finite element method. The sample function is chosen for the whole structure and the generalized stiffened matrix and load vector is derived by variation principle. It can decrease the calculation work and is suitable for applications in the engineering. |
