Posternak S. Influence of technological injure of concrete on the formation of cracks and hardiness curved reinforced-concrete elements on inclined sections

The object is technological injure curved reinforced - concrete elements, the aim - explanation of influence of technological injure concrete, on the formation of cracks and hardiness and work out recommendation of account technological injure, the methods are unitization of special and general methodic, the new approaches lies proposed and based for method quantity by estimation of the technological injure of the concrete models and the reinforced - concrete constructions, proposed differential meaning coefficient ?b4, result - work out proposal of the technological injure and proposed differential meaning coefficient ?b4 of dependence technological injure, all this result has been implicated at designing and producing curved elements on the reinforced - concrete factory Odessa railway, sphere of use is for designing of girders constructions.
