| Abstract: | An innovative sensor for monitoring the corrosion of steel reinforcement was designed based on the volume expansion of reinforcement corrosion and fiber Bragg grating strain theories.The quantitative relationship between the response of the sensor and the corrosion rate of steel reinforcement was established through accelerated corrosion experiments.The multi-objective optimization method was used for the layout of the sensors for monitoring the corrosion of steel reinforcement.Several sensors were embedded... |
