The formula is put forward for calculating the ultimate bond stress and the anchorage length of hot-rolled deformed bars and reactive powder concrete.
提出普通热轧变形钢筋与活性粉末混凝土的极限粘结强度与锚固长度的计算公式。
Results indicate that the ultimate bond stress between bars and RPC decreases with the increase of bar diameter or with anchorage length when bar diameter is the same.
研究表明：活性粉末混凝土与钢筋的极限粘结应力随着钢筋直径的增加而下降，钢筋直径相同时随着锚固长度的增加而降低。
The experimental results indicated that when 0.5%(volume fraction) steel fibers were added to HPC, the ultimate bond stress was improved and the corresponding slip was also increased.
试验结果表明高性能混凝土中添加0.5%（体积比）的钢纤维对极限粘结强度略有提高，峰值粘结应力对应的滑移有较大的增长；
