This paper presents an experimental study on bond behavior of longitudinal bars in hanging region of RC beam failed in bond. In order to realize the bond splitting failure, CFRP rods were used as longitudinal reinforcement instead of steel bars. Totally sixteen simply supported RC beams were tested in order to know the magnitude of bond stress in hanging region. The main test variables are stirrups ratio and additional embedment length in the hanging region, and stirrups ratio in the shear span. Based on the test results a model for predicting tension force at the support was presented. |
