钢筋疲劳性能试验研究

Testing research of fatigue performance of reinforced bar

为使国内市场与国际市场接轨 ,莱芜钢铁集团有限公司按英标BS44 49:1988进行了钢筋疲劳性能试验。试验中因试样夹持部位及试样表面存在问题 ,试验未能成功。采取改进试样形状等措施后 ,试样全部通过疲劳性能检验。

The fatigue performance of reinforced bar was tested according to UK BS4449:1988 by Laiwu Iron and Steel Group Co., to adapt the in international marks. But it wasnt successful because of the problems of the clamped position and surface condition of samples. At last, the fatigue performance condition of all samples reached the standard by reshaped the samples.
