| Abstract: |
| Bond constitutive relation between steel bar and concrete is one of the bases for nonlinear analysis of concrete structures. In this paper, a numerical simulation method is put forward to calculate bond constitutive relation. Interface element analysis was used to compile a three dimensional program. This program can be used to analyze single-end pullout test and double-end pullout test. The strain of steel, the slip between steel and concrete and the bond stress can be obtained. The results are compared with experimental data and good agreement is obtained. |
