The demand for rehabilitation using post-tensioning has recently increased. In this paper, an external post-tensioning method to strengthen flexural members is presented. Five reinforced concrete beam were fabricated and tested to evaluate the retrofitting effect provided by the external post-tensioning method employed in this study. The test results indicated that this rehabilitation method can easily applied and increase member capacity in a reliable manner. The test results were also compared with predictions which gave quite accurate estimation of member capacities.

The demand for rehabilitation using post-tensioning has recently increased. In this paper, an external post-tensioning method to strengthen flexural members is presented. Five reinforced concrete beam were fabricated and tested to evaluate the retrofitting effect provided by the external post-tensioning method employed in this study. The test results indicated that this rehabilitation method can easily applied and increase member capacity in a reliable manner. Various approaches for predicting stresses in unbonded tendons at ultimate were examined and the member capacities were compared to the predictions calculated by these approaches.
