Application of FBG Sensing Technology in Construction Industry - Fiber Bragg Grating Application - FBG Sensor Application - FBG Demodulator Application

Fiber bragg grating (FBG) sensing technology is a powerful and versatile tool that has found numerous applications in the construction industry. By utilizing optical fibers that are embedded within or attached to a structure, FBG sensors can detect and measure changes in strain, temperature, pressure, and other environmental variables. This technology has several applications in the construction industry, some of which are listed below.

 

Structural monitoring of buildings

FBG sensors can be embedded within the walls, floors, and columns of buildings to monitor the strain, temperature, and vibration of critical components. By continuously monitoring these parameters, engineers can detect any abnormalities or signs of deterioration in the building structure and take timely corrective measures.

 

Concrete curing monitoring

Concrete is a fundamental material used in the construction industry, and its proper curing is critical to ensure its strength and durability. FBG sensors can be used to monitor the temperature and strain of curing concrete. By monitoring these parameters, engineers can ensure that the concrete is curing correctly and take corrective measures if necessary.

 

Structural health monitoring of bridges

Bridges are critical components of our transportation infrastructure, and their safety and stability are of utmost importance. FBG sensors can be used to monitor the strain, temperature, and vibration of bridge components such as cables, girders, and piers. By continuously monitoring these parameters, engineers can detect any abnormalities or signs of deterioration in the bridge structure and take timely corrective measures.

 

Tunnel monitoring

Tunnels are often subject to environmental factors such as temperature, moisture, and vibration, which can affect their stability and safety. FBG sensors can be used to monitor the strain, temperature, and vibration of tunnel components such as walls, ceilings, and floors. By continuously monitoring these parameters, engineers can detect any abnormalities or signs of deterioration in the tunnel structure and take timely corrective measures.

 

Structural health monitoring of dams

Dams are critical infrastructure components used for water storage, flood control, and power generation. FBG sensors can be used to monitor the strain, temperature, and vibration of dam components such as walls, gates, and spillways. By continuously monitoring these parameters, engineers can detect any abnormalities or signs of deterioration in the dam structure and take timely corrective measures.
