Comprehensive Evaluation of In-Service RC Flexural Member′s Reliability Based on Attribute Mathematics

Abstract:

When the reliability analysis of in-service RC flexural member is carried on, an expert evaluation or AHP (analytical hierarchy process) for evaluation is commonly used, but human factors are big. This paper presents a comprehensive evaluation method of a existing RC flexural member’s reliability on the basis of attribute mathematics. According to the actual measured values of each index in the evaluation system, using a mathematical method to calculate weight, and build a comprehensive quantitative analysis model. Example analysis shows that this method can effectively identify and finely distinguish the reliability of in-service RC flexural members, which be much more objective and scientific compared with other previous methods.
