【摘要】：木結(jié)構(gòu)古建筑震后破壞狀態(tài)評估涉及眾多影響因子,且各因子間還存在相關(guān)性和不確定性.為提高木結(jié)構(gòu)古建筑震后破壞狀態(tài)評估的準確性,本文提出了基于模糊數(shù)學理論的評估方法.首先,將木結(jié)構(gòu)古建筑分為地基、基礎(chǔ)、上部結(jié)構(gòu)3個部分,結(jié)合其震害特點,選取13個指標作為評估因子;然后,由層次分析法確定權(quán)系數(shù)向量,采用隸屬函數(shù)和類比法構(gòu)造評判矩陣,建立三層次兩階段的模糊綜合評估模型;最后,以青城山黃帝殿為例,應(yīng)用該模型對其在汶川地震后的破壞狀態(tài)進行了評估.結(jié)果表明,本文方法能合理、較準確地評估震后木結(jié)構(gòu)古建筑的破壞狀態(tài),可為木結(jié)構(gòu)古建筑震后維修措施提供依據(jù).
[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.
