Abstract
The load-bearing part of a chimney pipe is a reinforced concrete shell of revolution. Its design model is a free-standing bar of the circular cross-section. It is recommended to conduct the analysis of cross-section guided by the branch construction norms VSN 286-90 [1]. This document was developed for “hand” calculations. Therefore, it contains simplifications which can be avoided. A method based on stricter presuppositions is suggested. Its basis is deformation plasticity theory. Concrete and steel are considered as nonlinear materials. The problem is reduced to a sequence of nonlinear equations which are solved by the method of variable parameters of stiffness. The approach does not require to predetermine a diagram of a limit state of the section, as it is formed in the process of solution. The criteria of a load-bearing capacity of the section are concrete and steel strains. Their maximum values are specified by construction norms.
