ABSTRACT:In this study the effects of bond-slip modelling in reinforced concrete structures based on analytical equations has been investigated. TEE joint from the cap beam to the column at a location connection of the bridge is considered. The work refers, especially to the implementation of reinforcing bars and bond-slip models between steel and concrete in the developed finite element program. In order to assess the bond-slip effect, the OpenSees finite element model of the TEE joint is constructed. CEB-FIP analytical method of bond-slip is considered with nonlinear behaviour parameters from materials. Also, It is performed Nonlinear time history and pushover analysis. Based on analytical equations, the results show that taking into account the bond-slip effects in the reduction of stiffness, ultimate capacity and energy dissipation.
