摘要: |
借鉴挪威DNV公司离岸混凝土结构设计标准(DNV-OS-C502)中的有关规定,计算了带肋钢筋与混凝土之间的疲劳黏结强度,得出了不发生黏结疲劳破坏时的钢筋允许疲劳应力幅[△os].在此基础上,对我国带肋钢筋锚固疲劳性能做出了对比评价,分析了提高带肋钢筋锚固疲劳性能的有效措施. |

Abstract: |
Firstly,the fatigue bond strength between ribbed bars and concrete were calculated according to the offshore concrete structures standard(DNV-OS-C502) by DNV(DET NORSKE VERITAS) in Norway.Then the allowable stress range of ribbed bars to avoid bond fatigue failure under fatigue loading was presented and discussed. The anchorage performance of ribbed bars with different grade embedded in concrete with different strength is evaluated under fatigue loading. |
Key words: ribbed bars bond anchorage fatigue |
