The Fiber Bragg Grating (FBG) sensor for rebar corrosion is a new type corrosion sensor, a complete monitoring system is consist of the corrosion sensors installed in different places of the structure, if the number of corrosion sensor is given, how to determine the corrosion number installed in different places, it’s a quantitative distribution problem. In this study, the quantitative distribution of rebar corrosion sensor in reinforced concrete T-beam bridge is studied. The corrosion sensors are installed in five places: T-beam top flange, ribbed beam, bent cap, bridge pier and abutment and bridge foundation. Based on Analytic Hierarchy Process (AHP), the AHP model of corrosion sensor distribution is proposed in this paper. This scheme reveals the influence on the distribution decision of corrosion sensor and this influence mainly comes from the indexes, the decision weight and the sensors number in different places are obtained.
