Determination of parameters and verification of the mathematical model of filled shells constructions on compressive foundation
There is presented a description of the numerical model of a cylindrical shell with filler supporting on the end face of the compressive foundation under eccentric loading. The method of the experimental determination of the parameters of the developed model was proposed. There is also given a theoretical model functionally connecting the parameters of foundation soil and structure size with the maximum horizontal force which the structure perceives without losses of the carrying ability of the foundation. The dependence is based on a task solution of the ultimate stress state of the soil foundation with accounting for development of sliding fields. The calculation results using the proposed formulas are in good agreement with the results of numerical modeling. It allows to use the proposed numerical model to estimate stress-strain state of cylindrical shells with fillers to calculate and design structures for hydroengineering, industrial and transport construction.
