| Title of the article | Experimental-theoretical method of estimating the shear compliance of plug joints of reinforced concrete columns |
| Abstract. | The article presents research results of the shear compliance of plug joints of reinforced concrete columns. Perfomed numerical and experimental investigation of the stress-strain state of the joints. Based on the investigations established schemes destruction plug joints – from the loss of shear resistance of concrete cover, from loss of adhesion between the solution in the well and the concrete columns, from the destruction of mortar and concrete by end fittings at their crush. All of the above characteristics included in the calculated expression of the shear compliance of plug joints columns. Shear compliance of plug joints of reinforced concrete columns is proposed to determine using deformation diagrams. For such compounds having several characteristic stages of work (up to the formation of cracks in the compound and after), the coefficients of compliance should be differentiated for each stage. The peculiarity of the method consists in that the joint deformation diagram is simplified to three fixed speed and displacement in the three characteristic points. Nonlinear joint work is accounted for by introducing the dimensionless coefficients ki, depending on results of experimental studies at each stage of the joint. Methodology converges satisfactorily with the experimental data. |
