METHOD OF DETERMINING STRENGTH OF ECCENTRICALLY COMPRESSED REINFORCED CONCRETE ELEMENT OF ANNULAR CROSS-SECTION Russian patent published in 2020 - IPC G01N3/12 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in designing, calculating and constructing a reinforced concrete structural element of annular cross-section. Summary: performing design resistance of reinforcement and concrete, determining concrete area in annular section and total area of all bars of longitudinal reinforcement, designation of inner (r₁, mm) and outer (r₂, mm) radii of reinforced concrete element of annular section, calculation of relative value of longitudinal force (α_n), index of concrete section saturation with longitudinal reinforcement (α_s), relative bending moment value (α_m), determining the design bending moment from the longitudinal force with allowance for the deflection of the element (M_η, kN⋅m) and ultimate strength of eccentrically compressed reinforced concrete element of annular cross-section with allowance for influence of deflection (M_scc, kN⋅m).

EFFECT: technical result is higher accuracy and faster determination of strength of eccentrically compressed reinforced concrete elements of circular cross-section during design, reduction of time, as well as wider field of use of the method of determining strength of eccentrically compressed elements and reducing the volume of the computer program to determine the strength of reinforced concrete elements.
