| Title of the article | Expansion options for unloading concrete with compressive stress |
| Abstract. | The purpose of researches is the establishment of analytical communication between tension and deformation parameters of concrete in case of axial loading of samples on unloading branches from compression tension. Research objects are: axial and cross deformations; coefficient of cross deformation; volume deformations. Cycles with different sizes of the maximum tension, including close to their limiting values taking into account a concrete dilatation are considered. Residual deformations when unloading are determined in increments of tension and deformations by a beam method. Connection between initial modules of elasticity of concrete and the module of deformations is established when unloading. Based on the experimental data analytical dependences of determination of sizes of residual deformations are constructed in case of partial or complete unloading. Comparisons of results of calculation for the offered technique with the experimental data obtained by authors are given. |
