Methodology for measuring the vertical displacements of bridges using fibre Bragg grating sensors

In many bridges, vertical displacements are one of the most relevant parameters for structural health monitoring in both the short- and long-terms. Bridge managers look for simple ways to measure vertical displacements of bridges, however it is difficult to carry out such measurements. In recent years with the advancement of fibre-optic technologies, fibre Bragg (FBG) sensors are more commonly used in structural health monitoring due to their outstanding advantages including multiplexing capability, immunity of electromagnetic interference as well as high resolution and accuracy. For these reasons, a methodology for measuring the vertical displacements of bridges using FBG sensors is proposed.
