中小学建筑抗震性能的模糊综合评判

Fuzzy Comprehensive Evaluation for Seismic Performance of Primary and Secondary School Buildings

在湖南地区中小学建筑抗震性能调研的基础上,针对中小学校建筑抗震现状,提出了用建筑的结构形式及其合理性、整体性、地震烈度等8个特征因素作为震害因子,并利用模糊理论建立多层次综合评价模型.采用不同方法确定了数量因子和状态因子的隶属度,并用层次分析法确定各因素权重,用最大隶属度原则结合加权平均法对中小学建筑作出模糊综合评判,最后通过实例验证了该方法的可靠性.

Based on seismic performance of school buildings in hunan,according to the present investigation,eight features of damage factor are proposed such as architectural structure forms and rationality,integrity,seismic intensity.By using fuzzy theory multi-level comprehensive evaluation model is established.The different methods are used to determine the membership of the quantity factor and status factor,and the weight of the each factor is analyzed by the method of the Analytic Hierarchy Process.With maximum membership degree of building combination with weighted average method makes fuzzy comprehensive evaluation,and finally verified by the examples that the method is reliable.
