Abstract
- To establish bonding stress—slip constitutive model between bars and grout concrete, 13 test specimens were employed to study the bonding behavior and the force transfer of bars adhered to grout concrete. The bonding stress development of bars adhered to grout concrete was analyzed. The local bonding stress—slip curve was obtained. Based on the test results, a new bonding stress—slip constitutive model between bars and grout concrete was proposed. The results show that the maximum bonding stress is not influenced by the bar bond length, but it is strengthened when the splitting strength of grout concrete is increased. The model matches the experimental results well, and the regressing coefficient equals 1.7.
