Research on durability evaluation of concrete in complex attack environment
Source abstract
Abstract
In this study on concrete durability under a single environment, considering the meteorological data to determine the environmental correction coefficient, the computational model of concrete ultimate durability life under one environment is improved. Damage is defined as the ratio of service life to ultimate durability life, and it specifies the failure of concrete structures when the damage comes to 0.8. The Analytic Hierarchy Process (AHP) is modified by replacing the conventional fuzzy scale to the priority of every single environment determined by the ultimate durability life span of each environment. The weight of every environment is settled by modified AHP and is used to improve Miner linear cumulative criteria. Then, the computational model of concrete ultimate durability life under a complex environment based on damage is established, the applicability of which is verified by comparing the prediction results and field data in Tianjin and Yantai ports. This paper also improves set pair analysis by dividing the stability range with comprehensive index connectivity, and then, the evaluation of levels of concrete durability stabilization is developed.
