ON ANALYSIS OF FRAMES MADE OF NON-ELASTIС COMPOSITE ELEMENTS WITH TERMAL ACTION TAKEN INTO ACCOUNT

Abstract

In this paper, the author solves the problem of calculating the deformation compressed- bent frames of inelastic composite elements having a variable cross-section and variable stiffness relations shift lengths for the effects of heat. The solution is based on the A.R. Rzhanitsin's theory of elastic composite bars. Static indeterminacy frames revealed by deformation. The expressions for the equivalent modulus of deformation, which takes into account the compressibility of the branches, the branches of the shear deformation of the material, form the backbone of the development of inelastic deformation in them, and the effect of temperature deformations.
