Abstract:
In this paper, tensile and pull-out reinforced concrete bond specimens are studied by the finite element mathod. The analysis is solely based on the basic mechanical properties of concrete and reinforcing bar, and other additional assumptions, such as distribution of cracks, bond stress-slip relationship, etc., are not necessary. The cracked concrete is considered as an orthotropic body, in which the tangent modulus along the diretion of cracks is taken as its initial value E. The shear modulus G’ on the cracked surface can be determined by a method described in this paper. The tangent modultts in the direction normal to the cracks is then obtained from E and G’. In the analysis, although it is assumed that the concrete is connected directly with the adjacent steel, the slip between both materials can be found approximately from the results of the finite element analysis. Three typical bond specimens are analyzed. The calculated results for the total elongation and the strain distribution of the embedded reinforeing bar, the strains and the distribution of the internal cracks in concrete as well as the bond stress-slip relationship are essentially in good agreement with the experimental data published in foreign literatures.
