| Title of the article | Shrink deformations in concrete and reinforced concrete elements |
| Abstract. | Most concrete subjects are exposed to shrinkage. In concrete constructions with small sizes shrinkage develops evenly, freely and own tensions do not rise up. In reinforced concrete constructions shrink deformations develop in the straitened terms due to internal connection of concrete with an armature and their size diminishes as compared to free deformations, but there are own tensions in a concrete and armature. In the process of exploitation power deformations and tensions from different loadings change not from zero values, but added up with their own sizes which in calculations and experimental researches, as a rule, are not taken into account. In the real work a connection is established between relative deformations of shrinkage of concrete and reinforced concrete standard with the symmetric reinforcing. On foundation results of experimental researches it is set, that free shrink deformations are increased from the beginning of measuring, and deformations of reinforced concrete standards only on t0 =4-5 days after release. Taking into account breaking of growth of deformation of reinforced concrete standard from shrinkage of concrete experimental information satisfactorily comport with a calculation. It is recommended to determine deformations of reinforced concrete element from shrinkage of concrete through the proper free shrink deformations, diminishing them on 25 %. |
