Calculation of Equal Strength Thick-Walled Concrete Cylinder with Free Ends

摘要

The article discusses radially inhomogeneous thick-walled cylindrical shells in which inhomogeneity may be due to various reasons(structure,the effect of the temperature field,etc.).Thick-walled shells are called equal-stressed,if the principle stress Oj in all points of the body is constant.In inhomogeneous body,in addition to the elastic modulus of a material,its strength can also variable.In accordance with the first theory of strength,if the stress Gj is variable and at each point the strength of the material is equal,then the thick-walled shell is called equal-strength.The article discusses the modelling of equal strength concrete thick-walled shell with free ends.
