Construct Safety Evaluation of the Ancient Masonry and Wood Buildings Based on Fuzzy Analytic Hierarchy Process Method
摘要
Abstract
The thesis considered structural complexity of ancient masonry and wood buildings and the fuzziness of safety evaluation factor. In order to accurately evaluate the safety of ancient masonry and wood buildings,the method based on fuzzy evaluation analysis was proposed. Firstly,the evaluated structure was divided into six relatively independent parts:foundation,timber column,timber beam, timber frame,roof structure and wall. And 27 evaluation indexes that affect the safety of each parts were established. Afterwards,the weights of each evaluation index were determined by analytic hierarchy process. The single factor fuzzy evaluation was based on the safety factor evaluation standards and two types of membership functions. Then,according to the principle of multi-level fuzzy comprehensive evaluation,the three levels and two stages of ancient masonry and wood buildings safety evaluation model was established. Finally,the reliability of the evaluation model is verified by an engineering example,and the evaluation result indicates that the operation status is relatively safe. Compared with the standard evaluation results,the result by fuzzy AHP evaluation method is closer to reality,which can provide a safety status basis for the renovation of ancient buildings.关键词
