The result is that the bond-anchorage property of ultra-fine grain steel bar is identical to that of common crescent ribbed bar,the anchoring length can be designed with the formula in code for design of concrete structures(GB50010-2002).

- 研究結果表明,雖然超細晶粒鋼筋屬推廣的新型工程材料,軋制工藝與傳統鋼筋不同,但超細晶粒鋼筋的粘結錨固性能與普通熱軋帶肋鋼筋(月牙紋)基本相同,其設計錨固長(cháng)度la仍可按現行《混凝土結構設計規范》GB50010-2002規定的公式計算;
