Bridge structural health evaluation based on multi-level fuzzy comprehensive evaluation

Abstract

Due to the complexity of usual bridges' indicator system, the inaccuracy and strong subjectivity of method appearance observation method, in this paper, factor weights are determined by analytic hierarchy processing. And multi-level fuzzy comprehensive evaluation is applied to evaluate the bridge structural health. On the basis of determining bridge structure indicators, an evaluation model is established. The evaluation results, which derived from evaluation model, are compared with expert evaluation results. And the compared result shows that the model can evaluate bridge structural health accurately. © 2011 Springer-Verlag Berlin Heidelberg.
