The tensile capacity of Stay Wire Assembly Fititngs is the tensile capacity of the round steel itself. The size equal to the cross-sectional area multiplied by the design value of tensile strength (140MPa) is the allowable tensile bearing capacity during design. Stay Wire Assembly Fititngs generally use Q235 steel, which is round.
We haven't seen the use of rebar, but it's okay if it is required by force. Rebar (Q345) has high strength, and it is not easy to make the thread of the nut. For the Stay Wire Assembly Fititngs, the buried depth is generally 25 times its diameter, and then a 90-degree hook with a length of about 120mm is made. If the bolt diameter is large (such as 45mm) and the depth is too deep, you can weld the square plate at the end of the bolt, that is, just make a big head (but there are certain requirements). The buried depth and the hook are to ensure the friction between the bolt and the foundation, so that the bolt will not be pulled out and damaged. Therefore, the tensile capacity of Stay Wire Assembly Fititngs is the tensile capacity of the round steel itself, and the size equal to the cross-sectional area multiplied by the tensile strength design value (140MPa) is the allowable tensile capacity during design.
