Abstract
Using an indoor pipe-cable-rod double-sided shear test system, tests for double-sided shear are carried out on three types of prestressed anchor cables and anchor cables with C-shaped tubes that eliminate the joint surface's resistance to movement. The shear failure characteristics and shear strength contribution of the anchor cable with C-shaped tube were compared and analyzed. For the anchor cable with C-shaped tube, the C-shaped tubes' geometrical specifications were altered and the effects of the C-shaped tubes' thickness and diameter on the anchor cables with C-shaped tubes' shear strength were investigated. The research results showed that the thickness of the C-shaped tube had a substantial impact on improving the ultimate shear capacity of the anchor cable with C-shaped tube. With the increase in the thickness of the C-shaped tube, the increment of the ultimate shear capacity showed an exponential growth trend. However, under the same thickness, the ultimate shear capacity had a negative correlation with the diameter of the C-shaped tube. In addition, the anchor cable with C-shaped tube was the subject of numerical simulation research using the three-dimensional numerical simulation program ABAQUS. The stress distribution and the development trend with increasing shear load were obtained. The simulation findings revealed that the numerical model and the outcomes of the laboratory tests were in good agreement, which might serve as a guide for future research.
