“…Miao and Zheng conducted an experimental study on 30 concrete pull-out specimens to evaluate the effect of bond stress on the local bearing capacity. There was an increase in the local bearing capacity of the concrete corresponding with an increase in the concrete strength and the load area [4]. Chen carried out a series of local compression experiments on 27 specimens strengthened by double-layer ring steel bars.…”

The cable saddle on top of pylon not only helps the main cable pass through the summit of design form, but also transmits the enormous force to the pylon. An imbedded cast iron cable saddle is going to be adopted for a single pylon and two span cable stayed bridge. A cast in situ concrete foundation, which is called a concrete mount in this context, bears the imbedded cable saddle underneath. Due to the cambered shape of the bottom face of this imbedded cable saddle, the local compressive stress distribution on the contact part with the concrete mount may not be uniform. The finite element method is used to investigate the feature of the local compressive behaviour for the concrete mount. According to the results, the reduction factor for nonuniform local compression is approximately 0.73. This cable saddle structure could meet the local compression bearing capacity via theoretical verification, and indirect reinforcement under local compressive pressure is recommended to keep the structure in good condition for the serviceability limit state.
