Abstract: Bending stresses caused by filling interstice cells in multi-bin reinforced concrete cylindrical silos are analyzed by means of a well-known finite strip solution for various radius-to-thickness and height-to-radius ratios. Numerical results show the influence of height-to-radius ratio in the solutions, setting a limit of that ratio above which bending analysis can be performed with simpler plane frame models with reasonable accuracy. It is shown that for shorter silos the plane frame model departs significantly from a more refined analysis. The finite strip method is shown to be useful for all aspect ratios used in practical applications.
