Method of calculation of limit loads on filled cylindrical shells

This article presents describing of the method of determining a limit horizontal load on gravity structures which are usually made of thin cylindrical shells with infill. Filled shell can be used as a part in construction of retaining structures, bridges, foundations, embankments, piers, breakwaters and others. The method is based on solving the problem of limiting stress state of the foundation soil, taking into account the development of slip fields. The theoretical model functionally connecting parameters of foundation soil and dimensions of the shell structure with maximum horizontal force is proposed. The structure perceives the load without loss of the bearing capacity of foundation soil. Defined load can be a model of the impact of lateral earth pressure on the structure, ice, waves, mooring forces, various kinds of technological load and other factors. The method of determination limit load is based on precise and strict mathematical solutions. This method can be used for verification of numerical models that are fully describing design features of construction, and estimation of required dimensions of the thin shell structure and foundation soil at preproject stage.
