| Abstract: |
This study aims to clarify the shear resistance mechanism of reinforced concrete haunched beams (RCHBs). Based on the new parameter of the bending position of tensile steel bars, three RCHBs without stirrups and three RCHBs with stirrups were tested. The results demonstrated that the bending positions of tensile rebars near the loading point highly influenced crack propagations and shear capacities in RCHBs. It was due to different contributions of arch action and stirrups in the shear resistance. The calculated shear carried by stirrups with the angles of diagonal shear cracks showed good correspondence with the experimental results. |
