FBG Sensing Technology for Building Structural Health Monitoring in the Civil Engineering Industry
Civil engineering is a vital industry that plays a crucial role in the development and growth of any nation. One of the most critical aspects of civil engineering is the monitoring and maintenance of the structural health of buildings, which is essential for ensuring public safety and preventing accidents. Fiber grating sensing technology is a powerful tool that has been developed to aid in this process. 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 building 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.

Importance of of Building Structural Health Monitoring:
Building structural health is an essential aspect of civil engineering as it ensures the safety of occupants and prevents catastrophic failure. Structural health monitoring involves the continuous monitoring and assessment of the structural condition of buildings, including the detection of any signs of damage or deterioration. By detecting these issues early, engineers can take corrective action to prevent further damage and avoid costly repairs.
Challenges of Building Structural Health Monitoring:
There are many challenges associated with building structural health monitoring, including the complexity and variability of building structures, the difficulty in accessing critical areas, and the need for continuous monitoring. Traditional sensing methods such as strain gauges, displacement transducers, and accelerometers are limited in their ability to provide accurate and reliable data over long periods of time. These limitations have led to the development of fiber grating sensing technology as a more effective solution.
What Problems Can Be Solved by FBG Sensing Technology:
Fiber grating sensing technology provides a more comprehensive and accurate solution for building structural health detection. By using FBG sensors, engineers can detect and monitor various physical parameters, including strain, temperature, pressure, and vibration. This technology can be used to detect early signs of damage and deterioration in building structures, allowing engineers to take corrective action before it becomes a more significant issue. Additionally, fiber grating sensing technology can be installed in critical areas that are difficult to access, such as inside concrete pillars and beams.
