Abstract
Steel silos are increasingly being publicized in the coal-fired power plant, due to the sudden transition of rectangular Steel silos shape, The mechanical performance is more complex than circular silos. It is found that little research has been done to rectangular Steel silos, so the most commonly used steel silos are circles and squares. They have advantages in mechanics, as the distribution of stress and deformation is uniform. However, the form of rectangular steel silo also often appears because of being confined by productive technique or layouts. In a previous study, analysis is still confined to the stage of elasticity. As steel has great plasticity, it is necessary to analysis in elastic-plasticity stage. Moreover the loads would lead to more deformations and the direction of the load is accordingly changed. The balance equation needs to re-establish on the equilibrium position of deformation. Taking the effects of geometrical nonlinearity into account is also important. Through the finite element software Ansys, the paper solves the problem of applying vary loads by adding surface effect element and researches the stress performance on the rectangular steel coal scuttle considering both materials and geometric nonlinearities. The paper shows the maximal Mises stress remains the same with the thickness added.
