FBG Sensing Technology for Building SHM in the Smart City Industry
Structural health monitoring (SHM) is a critical aspect of building maintenance in the smart city industry. SHM is the process of detecting, diagnosing, and evaluating the performance of a structure over its lifetime. By monitoring the structural health of a building, engineers and building managers can identify potential problems and take corrective action before a failure occurs.
Fiber grating sensing technology has emerged as a powerful tool for monitoring the structural health of buildings in the smart city industry. With the ability to provide real-time data on critical parameters such as strain, temperature, and vibration, fiber grating sensors offer numerous advantages over traditional monitoring methods. 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 help building structural health monitoring in the smart city 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.

Common Structural Health Issues in Buildings in the Smart City Industry:
Various types of buildings in the smart city industry are susceptible to structural health issues, including commercial buildings, residential buildings, bridges, and tunnels. Common issues include foundation settling, water damage, structural fatigue, and corrosion.
Why SHM is Critical for Buildings in the Smart City Industry:
Structural health monitoring is critical for buildings in the smart city industry for several reasons. First, it helps to ensure the safety of occupants and visitors. Second, it helps to extend the lifespan of buildings, reducing maintenance costs and increasing the return on investment. Finally, it can help to improve the energy efficiency of buildings, reducing carbon emissions and supporting sustainability goals.
Difficulties in Structural Health Monitoring of Buildings in the Smart City Industry:
Structural health monitoring of buildings in the smart city industry can be challenging due to several factors. First, buildings are often complex structures with many different components, making it difficult to monitor all critical parameters. Second, the harsh environment of buildings, including exposure to temperature and humidity fluctuations, can affect the accuracy of sensors. Finally, traditional monitoring methods can be expensive and time-consuming, making it difficult to implement a comprehensive monitoring program.
What Problems can be Solved by FBG Technology：
Fiber grating sensing technology can help to address many of the challenges of structural health monitoring in the smart city industry. By providing real-time data on critical parameters, fiber grating sensors can help to identify potential problems early, reducing the risk of failure. Additionally, fiber grating sensors are highly accurate and can operate in harsh environments, making them well-suited for building monitoring applications.
