Table 4 Proposed equations for bond element with respect to the level of rebar corrosion.
| Â | Maximum bond strength (Ï„ s, max , MPa) | Bond shear stiffness (D s , MPa) |
|---|---|---|
0 ≤ ΔW ≤ ΔWc | \( \tau_{s,max} = 0. 3 4\sigma_{B} - 1. 9 3 \) | \( D_{s} = \, 0. 2 40 7 { }\left( {\tau_{max} } \right)^{ 1. 7 5 3 4} \) |
ΔW ≥ ΔWc | \( \tau_{c,max} = \tau_{s,max} ( 1. 30 6e^{ - 0.0 9 4 8W} ) \) |
