【摘要】：木结构古建筑震后破坏状态评估涉及众多影响因子,且各因子间还存在相关性和不确定性.为提高木结构古建筑震后破坏状态评估的准确性,本文提出了基于模糊数学理论的评估方法.首先,将木结构古建筑分为地基、基础、上部结构3个部分,结合其震害特点,选取13个指标作为评估因子;然后,由层次分析法确定权系数向量,采用隶属函数和类比法构造评判矩阵,建立三层次两阶段的模糊综合评估模型;最后,以青城山黄帝殿为例,应用该模型对其在汶川地震后的破坏状态进行了评估.结果表明,本文方法能合理、较准确地评估震后木结构古建筑的破坏状态,可为木结构古建筑震后维修措施提供依据.
[Abstract]:The evaluation of damage state of ancient wooden buildings after earthquake involves many factors, and there is correlation and uncertainty among them. In order to improve the accuracy of post-earthquake damage assessment of ancient wooden structures, this paper puts forward an evaluation method based on fuzzy mathematics theory. Firstly, the ancient wooden structures are divided into three parts: foundation, foundation and superstructure. According to the characteristics of earthquake damage, 13 indexes are selected as evaluation factors. Then, the weight coefficient vector is determined by analytic hierarchy process, the evaluation matrix is constructed by membership function and analogy method, and the fuzzy comprehensive evaluation model of three levels and two stages is established. Finally, taking the Huangdi Temple of Qingcheng Mountain as an example, the failure state of Qingcheng Mountain after Wenchuan earthquake was evaluated by using the model. The results show that this method is reasonable and accurate in evaluating the damage state of the ancient wooden structures after the earthquake, and can provide the basis for the maintenance measures of the ancient buildings after the earthquake.
