The evaluation of the skeletal curve of RC beams with partially debonded longitudinal rebars was examined. Based on previous study, the skeletal curve model for RC beams with partially debonded rebars was assumed, and the evaluation formula for each characteristic point was proposed. It was confirmed that the calculated skeletal curve roughly corresponds to the experiment results.
In addition, a finite element analysis was conducted using the debonding length as a variable, and it was confirmed that the proposed evaluation formula can evaluate the change in the yielding deformation angle of the rebars due to differences in the debonding length.
