The present article presents a computational modelling of stiffened plates submitted to a uniformly distributed transversal load, allowing the numerical analysis of displacements and stress. The computational model was developed in the ANSYS software, based on Finite Element Method (FEM), using the SHELL281 finite element. This model was elaborated considering the symmetry boundary condition, allowing only one quarter of the stiffened plate to be numerically simulated. The simulations with this boundary condition demonstrated a computational processing gain in relation to the complete plate simulations. Besides, its use enabled the employment of more refined spatial discretization (meshes) than those used in models that consider the entire plate. In order to verify this computational model as well as to evaluate its accuracy in relation to the results obtained with the model that considers the whole plate, deflection and stress analysis were performed. The verification of the model was done using the independent mesh solution, obtained through a mesh convergence test. The results of the numerical model using the symmetry boundary condition demonstrated good accuracy over the whole plate computational model, both in the verification and in a comparative of the whole plate in relation to its equivalent with symmetry.
