Research on Evaluation Index System of Durability and Life Prediction for Concrete Structure

Abstract:

According to the different environment characteristics of China, the environments are divided into five types. Concrete durability evaluation index system is established in connection with different influence degree of durability factors in different environment. Combining with the properties of entropy, the weight of each influence factor index in a specific environment is determined by using Extension AHP, in order to avoid the disunity and incomplete of traditional AHP and eliminate the subjectivity to a certain extent in the process of index weight calculation. On this basis, the application software of the concrete durability evaluation and the life prediction for existing structure is programmed, which is applied in the living example. The analysis result shows that the application software has some important application value and practical significance, which can evaluate the durability of concrete structure effectively.
