摘　　要：历史建筑面临许多危险因素,为了更好地保护历史建筑,对其进行快速、准确的评估具有重要意义。本文提出了一种基于集对分析理论的木结构历史建筑结构安全综合评估方法。首先,对木结构历史建筑的结构安全程度进行划分;然后,从地基基础、上部结构2个部分构建了包含10个单项指标的木结构历史建筑的结构安全综合评价指标体系,并计算了各评价因子对应的安全程度的阈值,为了有效避免指标权重赋值的主观随意性,采用聚类权法计算各评价指标的权重;最后,应用集对分析模型对某历史建筑的结构安全进行了综合评估,通过与层次分析法、物元法等方法的评估结果进行比较,验证了本文方法的可行性,为木结构历史建筑的结构安全综合评估提供了新方法。The historical buildings face many dangers. In order to protect the historical buildings betterly,it has important significance in assessing them fastly and accurately. This paper presents a comprehensive assessment method for structure safety of the historical timber buildings based on the set pair analysis theory. Firstly,this paper grades the degree of structure health of the historical timber buildings.Secondly,establishes the evaluation index system which includes 10 single indexes from soil and foundation to superstructure,and calculates the threshold of the corresponding safety degree of each evaluation factor. In order to effectively avoid subjectivity and arbitrariness in assigning the index weight,this paper uses clustering weight method to calculate the weight of each evaluation index.Finally,the set pair analysis model is used to assess the structure safety of a historical building. Through comparison with the assessment results of the analytic hierarchy process（AHP）,the matter-element method and so on,the method in this paper is verified to be feasible,it provides a new way for the structure safety comprehensive assessment of the historical timber buildings.
