The results of studying the stability of the compressed pipe-concrete structures are given. Formulated the calculation principles and assumptions. Expressions for critical forces are given it is shown that the direct application of the formulas of existing regulations can lead to errors. The comparison of the results of calculation of critical forces at the given formulas with the experimental data is given.

The paper presents the results of testing full-size flexural pipeconcrete structures, which are used in the actual building objects. Technology of the structures met the construction conditions. Formulae for structural design of such constructions are presented. The formulae are based on the classical principle of structural mechanics as a condition of equilibrium of external and internal forces acting in the cross-section, as well as the conditions of equilibrium of these forces moments. Comparison of experimental and calculated data has been performed. Confirmation of the fact that the formulae developed give the results in good agreement with the experimental values is presented.
