Durability Evaluation Analysis of Reinforced Concrete Structures Based on Extension Method
Because of the facts of reinforced concrete structures materials and used environment, very severe durability problems occurred in reinforced concrete structures. Research on reinforced concrete structures durability has become one of the world-wide concern problems in structural engineering. Extension method based on matter-element theory and conjunction function is introduced to evaluate durability of reinforced concrete structures in this paper. The matter-element model for durability evaluation of reinforced concrete structures is established by chose seven evaluation indexes. Applying simple conjunction function to calculate the weight coefficient of evaluation indexes can reduce the error caused by subjective judgment, and makes the results more objective. The research indicates that extension method is reasonable and feasible in evaluating durability of reinforced concrete structures.
