Structural health monitoring system using FBG-based sensors for a damage-tolerant building

An example of structural health monitoring system using FBG-based optical fiber sensors for the damage tolerant building structure is presented. The damage tolerant building is equipped with several passive dampers for absorbing earthquake input energy, and the structural health monitoring system is focused to monitor performance of these dampers. FBG-based optical fiber sensor modules are developed to apply in structural health monitoring system for damage tolerant building structures. The system is verified on static measurement and dynamic measurement in earthquake.
