Abstract

In order to increase the multiplexing capacity of traditional fiber Bragg grating (FBG) sensor and to provide more abundant information support for the structural safety evaluation, structural strain experiment was carried out based on on-line continuous preparation technique for identical and weak FBG. According to uniform strength cantilever beam experiment, good force sensitive linearity and repeatability of naked weak FBG was verified, which indicated the feasibility for structural strain test. The experimental results of scaled-down model showed that the layout configuration for weak FBG was reliable and responses of weak FBG packaged by optical fiber ribbon and theoretical values were consistent in the whole process of minute heap load by masses.
