Reinforced concrete beam-column joints are a major source of deformation of reinforced-concrete-framed structures, which often cannot be neglected. The most important sources of deformation of these joints are shear deformation and slip of the longitudinal reinforcing bars of beams and columns inside the joint. The latter, which are addressed in this paper, cause the increase of the rotation at the end sections of beams and columns. To simulate this phenomenon in the quasi-static monotonic loading case, the paper develops simple, discrete, one-dimensional (1-D) models for straight and bent anchorages, which are based on previous experimental and analytical studies. Next, numerical procedures specifically established to solve these models are applied to compute the behavior of straight and... bent anchorages for MC2010 bond stressslip relationships. Finally, these numerical results are compared to experimental results obtained by other authors, showing a good agreement, particularly in the small and medium slip ranges.
