FBG Sensing Technology for Bridge Structural Health Monitoring in the Civil Engineering Industry
Bridge structural health monitoring is the process of monitoring the behavior and performance of bridges to ensure their safety and reliability. The use of fiber grating sensing technology has revolutionized bridge health detection, allowing engineers to monitor various parameters in real-time.
Fiber grating sensing technology has been widely used in the civil engineering industry, particularly in bridge structural health monitoring. As bridges play a critical role in transportation infrastructure, their safety and reliability are essential. Fiber grating sensing technology offers a reliable and efficient way to monitor the health of bridges and ensure their long-term safety and sustainability. In this article, we will discuss the problems that fiber grating sensing technology can solve，and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support bridge structural health monitoring in the civil engineering industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Necessity of Bridge Structural Health Monitoring and Challenges:
Bridges are subject to constant wear and tear due to weather, traffic, and other environmental factors. Over time, this wear and tear can lead to structural damage, which can cause safety risks and operational issues. Regular structural health monitoring is necessary to identify these potential problems before they become major issues. However, traditional monitoring methods can be time-consuming and costly, making it difficult to monitor the health of bridges effectively.
Problems Solved by FBG Sensing Technology:
Fiber grating sensing technology offers a reliable and efficient way to monitor the health of bridges in real-time. It allows engineers to measure various parameters, such as strain, temperature, and displacement, in multiple locations on the bridge structure. This real-time data enables engineers to identify potential problems early and take corrective action to prevent structural damage.
