摘要

摘要: 根据声发射信号参数特征评估砌体结构损伤状态对于砌体结构的健康监测是一个创新的方法。进行了砖砌体试件的轴心受压试验和在役砌体砖墙的原位轴压试验,分析了在试验过程中声发射振铃计数、能量和峰值频率的特征。结果表明:声发射参数变化特征与砌体损伤的演变过程相对应,在砌体损伤的不同阶段,声发射参数呈现出了不同的变化特征;在试件的破坏阶段,声发射信号特点为高能量和低频率,这些特征可以为评估砌体结构状态和结构安全预警提供支撑和指导。

Abstract: Evaluating the damage state of masonry structures based on the characteristics of acoustic emission (AE) signal parameters is an innovative method for health monitoring. The axial compression test of the brick masonry specimen and the in-situ axial compression test of the in-service masonry brick wall were performed. The characteristics of the AE ring counts, energy, and peak frequencies during the test were analyzed. The results showed that the AE parameters presented different characteristics, and the variation characteristics were in good agreement with the evolution process of masonry damage. In the failure stage of the specimen, the AE signals were marked as high energy and low frequencies. These characteristics could provide support and guidance for assessing the state of masonry structures and early warning of structural safety.
