The present article is concerned with the peculiarities of redistribution of forces in statically indeterminate reinforced concrete beams. Traditional continuous framing schemes allow for redistribution of bending moments within fairly narrow limits, what severely restricts their efficiency, especially under high loading. Thereupon, new effective construction solutions of continuous reinforced concrete beams have been proposed in this article. These effective construction solutions are obtained on the basis of a scheme with equal moments by changing the stiffness of the beams along their length. Utilizing the method of design resistance of reinforced concrete, there has been offered to search for effective design parameters and enforcement of continuous beam constructions. The method of design resistance of reinforced concrete is based on the nonlinear deformation model, which uses deformation curves for concrete and reinforcing steel. In reliance on currently accepted hypotheses and prerequisites, the authors of the article have laid down the geometric parameters, which allow to reduce calculation sets of equilibrium equations to the clear delineation of geometrical and physical–mathematical cross-sectional parameters. This allows tabulation of the necessary parameters and significantly simplifies all calculations of deflections of reinforced concrete elements. This paper provides a calculation example of a continuous double-span beam with central prop based on the proposed calculation procedure. The paper shows the effectiveness of the proposed construction solutions of beam systems with equal moments in comparison with the traditional ones.
