Abstract
The article discusses the use of a device for stress relieving in the manufacture of cold-shaped reinforcement armature with a diameter of 10 mm, which makes it possible to increase its plastic characteristics. Ductility or deformability is a complex characteristic of the reinforcement, which directly affects the safety of buildings and structures.
From modern understanding point of view of the operation of reinforcement in reinforced concrete two characteristics are used for the ductility characteristics: the ratio of the time resistance to rupture to the yield point and the total relative elongation at maximum load ratio of tensile strength to yield strength
Traditional technologies allow to produce stable cold-formed reinforcement armature only of the ductility class «A». Application of special types of profile and «non-traditional» relief devices potentially will allow the production of cold-worked reinforcement armature of class of ductility «B».
