本文介绍了一种利用时间反转技术和锆钛酸铅（PZT）传感器对建筑行业中广泛应用的引脚连接结构进行加载状态监测的有效方法。制作了一种带销连接的张力可控结构，并进行了实验。两个PZT贴片传感器分别安装在引脚和连接的结构表面上。在实验中，通过改变引脚连接上的张力进行时间反转过程，实验结果表明，PZT传感器检测到的聚焦信号峰值随着引脚连接上的载荷的增加而增加。此外，整个实验过程重复了7次，以验证所提出方法的重复性和一致性。随后，在高扰动环境下验证了实验结果的可靠性。试验结果表明，所提出的PZT传感器与时间反转技术相结合的方法在实际应用中具有很大的应用潜力，特别是在严重干扰环境下的索杆桥索-桥面连接载荷监测中。
An effective approach using time reversal technique and lead zirconate titanate (PZT) transducer was described in this paper to monitor the loading status of pin-connected structures, which are widely used in the construction industry. A tension-controllable structure with a pin connection was fabricated and used for experimentation. Two PZT patch sensors were mounted on the pin and on the connected structural surface. In the experiment, the time reversal process was performed by varying the tension on the pin joint, and the experimental results demonstrate that the peak value of the focused signal, detected by the PZT sensor, increases with the load on the pin connection. In addition, the entire experimental process was repeated seven times to verify the repeatability and consistency of the proposed method. Subsequently, the reliability of the experimental results was verified in an environment with high disturbances. All the test results show that the proposed method using PZT sensors along with the time reversal technique has potential to be employed in practical applications, especially monitoring the load of a cable-deck connection in a cable-strut bridge in an environment with severe disturbances.
