Abstract EN
As a FEM for reinforced concrete bond-slip problems, one important feature of the typical double spring joint element method is the selection of the normal stiffness, which may cause the mutual embedding problem and bring challenges to the calculation.
In this paper, a novel single spring joint element method based on the mixed coordinate system is proposed to simulate the interaction of two materials.
Instead of choosing the normal stiffness arbitrarily, the proposed method makes DOFs of two materials in the normal direction equal to ensure deformation compatibility.
And its solid elements for the concrete are solved in global coordinate system, while the beam elements for the steel bar are solved in local coordinate system.
In addition, the proposed method can also be applied to RC structures with irregular arrangements of steel bars.
Numerical examples demonstrate the validity and accuracy of the proposed approach.
Furthermore, the bond model is applied to RC beams with the description of the damage process.
