On the Calculation of the Strength of Inclined Sections of Reinforced Concrete Elements with Different Cross-Section Shapes

The current SP 63.13330.2018 contains methods for calculating the strength in inclined sections only for elements with a rectangular cross-section shape. The article considers the issues of calculating the strength of inclined sections of reinforced concrete elements with different shapes of their cross-section. A method for taking into account the shape of the cross-section of elements when calculating them along a concrete strip between inclined sections, when calculating the action of transverse forces and the action of bending moments is described. Dependences are given for calculating elements with a T-bar, I-beam, round, annular and trapezoidal cross-section shape, as well as with a cross-section in the form of a cross. A comparison of the results of calculating the strength of inclined sections of elements made according to different methods, as well as a comparison of the calculation results with experimental data, is presented. In general, the results obtained for calculating the strength of inclined sections of reinforced concrete elements with different cross-sectional shapes are consistent with experimental data.
