Abstract
To the calculation of reinforced bending elements of building structures from polymer composite materials with multimodulus nonlinear elastic matrix
Incoming article date: 14.06.2022An engineering technique for determining the bearing capacity of reinforced bending elements of building structures made of a binary composite material with a multi-modulus, nonlinearly elastic polypropylene matrix and powder filler is described. Information about various approaches to solving the problem proposed by other researchers is given. The author's method for obtaining the predicted physical and mechanical characteristics of binary composite materials is described, which gives more accurate results compared to known approaches. An algorithm for iterative refinement of the geometric characteristics of structural elements with an arbitrary cross section and a non-linearly elastic matrix has been developed. A computer program is described that automates the process of characterization, examples of specific cross sections are given. The possibility of refining the geometric characteristics of elements in the direction of their increase is proved.
