【摘要】 建筑结构选型的问题求解过程包括方案生成、方案评价和方案决策3个设计阶段,其中方案评价阶段是决策者建立影响结构选型各个属性的因素层次关系,根据方案分析的数据及专家的经验确定结构型式方案的各项评价指标的具体数值,为下一阶段的方案决策提供依据.方案评价的对象、指标体系、权重以及专家的评语等涉及到大量的模糊性信息,采用模糊集理论和模糊推理方法可以有效地处理方案评价的模糊设计信息.提出了在建筑结构选型设计过程中采用模糊推理系统对拟定方案进行评价的方法,构造了用于结构选型的FIS(FuzzyInferenceSystem)评价系统,并以高层建筑结构选型问题为例论述了其建造与推理过程.更多还原

【Abstract】 The selection of structural design schemes consists of generation, evaluation and finalization of structural design schemes, and for evaluation of structural design schemes, a hierarchical structure must be established with all the factors having effect on the attributes of structural designs taken into consideration so that specific values can be worked out using data analysis and expertise as the bases for the decisionmaking process.The index system, weights and experts’ comments used for evaluation of structural design schemes involve a lot of fuzzy information, and these fuzzy design information can be efficiently processed using fuzzy set theory and fuzzy inference. A fuzzy inference system(FIS)has been proposed for evaluation of structural design schemes. The construction and inference process is illustrated by the evaluation of highrise building structural design schemes.更多还原
