基于TFN-AHP赋权的木结构建筑可靠性评估研究
为科学客观地确定木结构建筑的可靠性,构建一种基于三角模糊数层次分析法(TFN-AHP)的模糊综合评估方法。依据环境因素对木结构建筑的构成要素造成的影响选取木材开裂、受潮、虫蛀、强度、腐朽、构件变形、连接件松动及锈蚀共8个参数构成评估指标体系;运用TFN-AHP为各项指标分级赋予权重,并依据GB 50005—2017《木结构设计标准》等划分可靠性评估等级;将指标分类处理以确定各指标隶属向量,依据模糊综合评估原理得出木结构建筑可靠性等级;并结合牡丹江市某木结构建筑进行工程实例分析,为木结构建筑的维修加固工作提供科学指导。

Research on Reliability Evaluation of Timber Building Based on TFN-AHP Weighting
In order to scientifically and objectively determine the reliability of timber buildings, a fuzzy comprehensive evaluation method based on triangular fuzzy number and analytic hierarchy process (TFN-AHP) is constructed. First, according to the influence of environmental factors on the components of timber building, 8 parameters are selected to form the evaluation index system: wood cracking, wood dampness, wood moth, wood strength, wood decay, member deformation, loose connection and corrosion. Second, TFN-AHP was used to assign weights to each index, and the reliability evaluation grade was divided according to the "wooden structure design standard". Then, the indexes are classified to determine the membership vector of each index, and the reliability grade of timber building is obtained according to the fuzzy comprehensive evaluation principle. Finally, the paper analyzes a timber building in Mudanjiang city as an engineering example, which can provide scientific guidance for the maintenance and reinforcement of timber building.
