| Abstract: | Based on the results of pull out test of 72 cold draw spiral bars, the bond and anchor property between the bar and concrete and the factor such as the tensile strength of concrete, the thickness of relative protective layer and the relative anchoring length that influence the average bond strength are discussed in detail. The formulas to calculate the average bond strength and the minimum anchoring length and the value of minimum anchoring length are given. |
