摘要
用模糊综合评判法对建筑物进行了震害预测。在进行单因素评判时,较为精确地考虑了单因素中不同量值的影响,并用信息分配法建立了单因素评判的模糊关系矩阵。然后将各单因素的评判结果汇总成多因素评判的模糊关系矩阵,进行多因素模糊综合评判。最后用格贴近度对评判结果进行识别,以确定建筑物的破坏等级。文末以单层空旷砖房的震害预测为例,说明了本文方法的应用。
A fuzzy comprehensive evaluation method for earthquake damage prediction is
presented in this paper. The features of this method are that magnitudes in single factor
are accurately considered when the single factor evaluation is doing, and a fuzzy relation-
ship matrix of single factor evaluation is formed by using information distribution meth-
od. After that, the multifactor fuzzy comprehensive evaluation is conducted and its fuzzy
relationship matrix is formed by collecting the results of single factor evaluation. To give
a grade of earthquake damage in the building, the lattice similarity is used to recognize
the evaluation result. Taking the spacious single story brick masonry building as
example, the application of this method illustrated.
