Abstract: The pull-sensitizing of conductive film resistor was applied to monitor the process of strain changes and crack generations in bridge structure. The conductive film resistor was attached to the surface of the concrete structure for its health monitoring. The concrete beam was made in the laboratory, and the conductive film together with strain gauge was wired in the underside of the beam to carry out the crack monitoring tests. The test results were compared with that of ANSYS finite element simulation. The quantitative relationship between strain and the change of the resistance of the film was identified within the elastic deformation range before the appearance of the crack. When the crack occurred on the structure surface, the instantaneous resistance increased dramatically, and the relationship between the resistance of the film and the crack width was determined. The resistance mutations were observed to determine the occurrence time and location of the crack. Then, the development of the crack was continuously measured.

Key words: road engineering, health monitoring, pull-sensitizing effect, structure cracks
