THE APPLICATION OF EXTENSION INTERVAL FUZZY COMPREHENSIVE JUDGEMENT METHOD ON ASSESSMENT OF ENGINEERING STRUCTURE

The Analytic Hierarchy Process approach is often applied to the assessment of engineering structure, however it can not reflect the uncertainty and fuzziness of the index. Based on fuzzy comprehensive judgement method, various factors which impact comprehensive evaluation of reinforced concrete structure are systematized and clear. By introducing extension interval and constructing fuzzy and uniform judgment matrix, weight intervals of factor indexes are got in different layers. And evaluation result is obtained by multilevelly fuzzy processing, the grade of engineering structure is determined by the maximal subjection grade. In this paper. the office building of maanshan steel company is evaluated. The result proves that the assessment of engineering structure is more reasonable and more practical by introducing extension interval.
