摘要

本文论述了在渐进腐蚀条件下对钢筋混凝土梁进行的无损实验测试。报告使用电势、超声波和低频振动技术进行了一系列实验。电势和自然频率用于描述和监测腐蚀过程的初始状态。事实证明，P 波速度测量可以有效地定量评估腐蚀程度。使用建议的损伤指数和诊断框架进行早期损伤检测的可能性很高，有望应用于钢筋混凝土构件的无创诊断中。

Characterization of Corrosion-Induced Fracture in Reinforced Concrete Beams Using Electrical Potential, Ultrasound and Low-Frequency Vibration

The paper deals with the non-destructive experimental testing of the reinforced concrete beams under progressive corrosion. A series of experiments using electrical potential, ultrasound and low-frequency vibrations techniques are reported. Electrical potential and natural frequencies were used to characterise and monitor the corrosion process at its initial state. The P-wave velocity measurements were proved to be effective in quantitative assessment of the level of corrosion as it progresses. The possibility of early detection of damage using a proposed damage index and diagnostic framework is promising for possible applications in the non-invasive diagnostics of reinforced concrete elements.
