摘　　要：基于线性累积疲劳损伤理论及作者一些相关试验数据,建立了锈蚀钢筋混凝土梁的疲劳累积损伤度修正公式,为锈蚀钢筋混凝土结构的进一步研究提供依据。Based on the linear fatigue cumulating damnification theory and some experimental datas , the calculation of fatigue cumulating damnification intensity was also modified after the corrosion rate which was the most important factor for the fatigue lifespan was considered. The investigation of the corroded reinforcement concrete structure in reality could obtain some support from this experiment.

关 键 词：疲劳累积损伤 疲劳刚度 锈蚀钢筋混凝土梁
