Abstract:
Aimed at finding out the measure effect of fiber grating sensor under different loads, the Pushover and pseudo-static experiment were carried out for three reinforced concrete bridge pier models; the strains of the steel bar and concrete as well as horizontal displacements on top of the model were measured simultaneously by using the fiber grating sensor and the strain gauge(9 groups measure contrast tests).The simultaneous measured values and the time-strain(displacement)curves coming from two types of sensor were contrasted, and the points with more dispersion were analyzed according to the fact of experiment. The results demonstrate that the two groups of data are well corresponding. It is dependable and effective that the fiber grating sensor can be applied to measure the strain and displacement. Finally, authors put forward some advices which needed to pay attention to research of this type of experiments in future.
