| Research Abstract |
A novel packaged long-gage FBG (Fiber Bragg Grating) sensor for health monitoring of civil structure has been developed and verified to have the ability to obtain effective macro-strain distributions. Experimental study on application of PVDF (polarized polyvinylidene fluoride) film as a crack detection sensor was conducted to detect occurrence and crack propagation of specimen and RC beams. Moreover, the neural network system which was built based on response information of multiple locations is able to grasp damage location and damage extents in structural health monitoring (SHM) of civil structures.
