【摘要】 从结构方案设计的角度,建立了工程实例信息的统一表征模型,收集获取了国内外1008个高层结构工程实例信息。在此基础上,利用关系数据库技术建造了高层结构实例库及其管理系统,实现了实例数据录入、修改、删除、查询、统计和知识发现等功能。最后结合高层结构智能选型的实际,给出了基于实例库的定量型与模糊型结构选型规则的挖掘过程与方法,同时还构建了定量属性的模糊区间划分及其模糊化方法,分析探讨了基于Apriori算法的关联分析方法在工程智能设计等方面的可能应用。上述工作为挖掘与充分利用已有工程实例中的知识信息,提高结构设计效率、质量与智能化水平等提供了新的途径、方法与手段等的支持。更多还原

【Abstract】 In this paper, a unified expression mode of building case information is set up for structure scheme design, and 1008 highrise building cases are collected. A practical case database and its management system are developed by relational database, which includes the functions of data input, modification, erasion, inquiry, statistics and knowledge discovery, etc. With the actual intelligence form-selection of highrise buildings, the data-mining process and method based on the case-base quantification and fuzzy structure form-selection rule are addressed. In the meantime, the fuzzy interval division and its fuzzification method for quantitative attributes are set up and the potential application of Apriori algorithm -based association analysis method in intelligent building design is discussed. Based on the above results, new technical methods are presented to make full use of engineering knowledge information of practical case, and promote the efficiency, quality and intelligent standard of structure design.更多还原
