Comprehensive Evaluation on the Durability of Concrete Structure Base on Uncertain Measurements

It is unascertained and non-linear that evaluates the durability of concrete structure factors and their impact. Accordingly, selected the most impact on the durability of concrete structures to assess factors as indexes, established unascertained measure comprehensive evaluation model. Applications by the model showed that the assessment result can objectively reflect the durability of concrete structure, which provided a new method and way for assessment of concrete durability and has theoretical and practical value. Due to the ordered division of assessment space, the unascertained measure model improves distinguish level. It has reliable assessment result and is a practical model.
