对钢筋混凝土结构锈蚀损伤定位进行了研究,以频率变化平方比作为锈蚀损伤参数,从理论上证明该参数是锈蚀损伤位置的函数。锈蚀钢筋混凝土结构试验结果表明预测的损伤位置和实际的损伤位置较一致,模态参数用于检测混凝土结构构件中的损伤,为大型结构的鉴定和评估提供了新的途径。
The corrosion damage location of reinforced concrete structure was studied. The square root of frequency variation was taken as the parameter of corrosion damage, and it was theoretically proved that this parameter is a function of the location of corrosion damage. The test results of corroded reinforced concrete structure show that the predicted damage location is consistent with the actual damage location. The modal parameters are used to detect the damage in concrete structural members, which provides a new way for the identification and evaluation of large structures.
