How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Reinforced concrete compressed elements with a small eccentricity and methods for calculating their strength are considered. A method for determining the deformation of the longitudinal reinforcement furthest from the longitudinal force is proposed. At the same time, the use of a single formula for s is ensured during the transition from an alternating deformation plot to an unambiguous one. Empirical dependence is used to determine the height of the compressed zone, which avoids solving the quadratic equation. In elements with a small eccentricity, symmetrical reinforcement is used, for this case the equation of equilibrium of longitudinal forces is derived.
