Technological cracks which is the structures parameters of concrete define of the technological injury of construction and their – exploitative reliable.
The coefficients of technological injury on typical line have been proposed and based for method by estimation of the technological injury of the concrete models and the reinforced-concrete constructions.
The influence quantity mineral fillion and quality have been studied and set on technological injury of concrete, physics-mechanical characteristic of concrete, on value relative across strength of formation cracks and relative altitude by compressed zone, on value relative carrying capacity of concrete and coefficient цb4.
The character of formation and development normal and inclined cracks in reinforced-concrete beams has been shown what on first stage of development of inclined cracks what and normal had been developing on the trajectories of technological cracks. Then exploitation cracks had been developing or by turning into main line or by acrossing structures pulleys.
The influence of technological injury of concrete have been set on physics-mechanical characteristic of concrete, relative across strength of formation cracks and altitude by compressed zone, on relative carrying capacity of concrete and coefficient цb4.
In accordance with the receive results the verification of curved members by carrying capacity with account of technological injury of concrete would be recommending to conduct by differential dependence of the change of quantity and quality by the mineral fillion.
Keywords: concrete, reinforced-concrete, curved elements, technological injury of concrete, formation of crack, hardiness, inclined sections, accounts.
