| description | In this paper, the effect of cable indent shape on the shear behavior of concrete-cable attachment surface has been investigated using PFC2D. Firstly, calibration of PFC was performed using the Brazilian experimental test and uniaxial compression test to reproduce the concrete sample. After calibration of PFC2D, punch shear tests were simulated by creating a rectangular concrete model in PFC2D. Numerical models with a dimension of 100mm *100 mm were prepared. cable with different indent shape was inserted within the model. The punch shear test condition was added to the model. The normal load was fixed at 3.7 MPa (σc/10) and shear load was applied to the model till failure occurred. The results show that tensile cracks are the dominant mode of failure that occurs in the attachment surface. Also, the shape of the attachment surface has an important effect on the failure mechanism of concrete. The shear strength increased by increasing both of the bolt indent width and length. |
