碳纤维布加固钢筋混凝土梁徐变后的疲劳性能研究
Fatigue behavior of reinforced concrete beams strengthened with carbon fiber sheets after creep
摘要
Abstract
The long - term behavior of bonding surface of concrete beams reinforced with carbon fiber sheets, especially, the fatigue behavior under long - term load is the key factor for its successful use. The experimental investigation was conducted about the fatigue behavior of reinforced concrete beams strengthened with carbon fiber sheets after creep. It is shown that the reinforced concrete beams strengthened with carbon fiber sheets have better fatigue behavior. The deflection of strengthened beams which had not crept reduce 9％ ～ 18％ to that of beams which had not crept. The deflection of strengthened beams which had crept reduce 9％ ～ 18％ to that of beams which had crept. The full analysis of fatigue is presented based on the residual strain, fatigue elastic and fatigue strength degradation, and the calculating results are accordant to observed data.关键词
