Abstract
The method of calculating the bearing capacity in the normal section of biaxial bended reinforced concrete T-section crane beams is developed. The problem of difficulty applying the deformation model in the study of biaxial deformed elements is successfully solved by the introduction of the rectangular stress distribution in a concrete compressed area and deformative criterion of strength. Analytical formulas are derived for the determination of all unknown parameters when calculating for biaxial bending: the neutral axis depth, the angle of inclination of the neutral axis, and the internal bending moment. The method is proposed for calculating beams with a trapezoidal shape of the concrete compressed area, taking into account all provisions of the effective normative documents and, unlike the existing ones, allows performing calculations without the use of numerical methods. The developed method of calculating provides the necessary accuracy of the calculations and can be implemented in the form of an engineering algorithm.
