ABSTRACT The effect of uniaxial compression on the development of damage in reinforced concrete has been studied, using the parameters of the electric response to elastic impact. During the quasistatic loading of the samples at a constant speed, a weak impact is produced on the lateral surface of the sample during a specified period of time, and an electrical response to this impact is measured. Consistent patterns in the changes of the parameters of the electric response with various loads have been identified. Computer simulation of the parameters of elastic waves in reinforced concrete subjected to mechanical impact has also been used. Based on the simulation, the parameters of the electric response have been calculated using the mechanoelectrical transduction model. Good consistency of theoretical and experimental signals confirms the relationship between the electric response and the interaction of elastic waves and fractures in reinforced concrete caused by uniaxial compression. Based on the electric response data corroborated with the computational results, diagnostic criteria have been obtained which make it possible to predict failure of reinforced concrete structure long before it occurs.

使用对机械冲击的电响应参数检测受单轴压缩的钢筋混凝土的退化

摘要 使用对弹性冲击的电响应参数，研究了单轴压缩对钢筋混凝土损伤发展的影响。在以恒定速度对样品进行准静态加载期间，在指定的时间段内在样品的侧面产生微弱的冲击，并测量对该冲击的电响应。已确定电响应参数随各种负载变化的一致模式。钢筋混凝土中受到机械冲击的弹性波参数的计算机模拟也已被使用。在模拟的基础上，使用机电转换模型计算了电响应的参数。理论和实验信号的良好一致性证实了电响应与单轴压缩引起的钢筋混凝土中弹性波和裂缝的相互作用之间的关系。根据与计算结果相一致的电响应数据，已经获得了诊断标准，从而可以在钢筋混凝土结构的失效发生之前就对其进行预测。
