Simulation of the Effect of Cable Indent Shape on the Shear Behavior of Concrete-Cable Interaction Surface using PFC۲D abstract
In this paper, the effect of cable indent shape on the shear behavior of concrete-cable attachment surface has been investigated using PFC۲D. Firstly, calibration of PFC was performed using the Brazilian experimental test and uniaxial compression test to reproduce the concrete sample. After calibration of PFC۲D, punch shear tests were simulated by creating a rectangular concrete model in PFC۲D. Numerical models with a dimension of ۱۰۰mm *۱۰۰ 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 ۳.۷ MPa (σc/۱۰) 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.
