Hello
Dear all
I am struggling with modeling bond-slip of RC a element (beam or column) using OpenSees. I already know that the best way to consider slippage in a rebar-concrete interface is to modify the steel strain-stress behavior in order that considers the extra elongation due to slippage. Accordingly, the modified elongation appears on the bilinear behavior of steel (e.g. Hystertic Material) (Fig. 1). However, I don't know how to reach the modified Strain(ε)-Stress(fs) relationships of steel by incorporating a common (e.g. CEB-Fip) local slippage(s)-bond (τ) behavior (Fig. 2)?
I do appreciate it if there are papers that used local bond-slippage behavior to consider slippage in RC structures, suggest those to me?
Thank you very very much.
