【摘要】 为了提高结构损伤评估的准确性,应用集对分析理论和方法,以整体损伤指数、最大层间位移角、滞回耗能循环次数和楼层能量集中系数作为评价因子,建立了损伤评估的集对分析模型,提出了基于集对分析理论的钢筋混凝土结构地震损伤综合评估方法.该方法将各待评定的样本值与分级标准形成对子,逐个比较其共有特性、相反特性及差异特性,从不同侧面刻画2个集合的联系与关系(即集对分析),从而比较准确地判别钢筋混凝土结构地震损伤的程度.并对4种不同型式的结构进行分析,验证了该方法的合理性和有效性.更多还原

【Abstract】 In order to assess structural damage with complete consideration of various parameters and enhance the accuracy of assessment,a comprehensive method for seismic damage evaluation on reinforced concrete structure,which took internal damage index,maximum inter-storey drift,number of inelastic cycles and energy-concentrated quotient as evaluation factors,was established based on Set Pair Analysis(SPA)theory. This method was constructed by using sample values compared with the value of standard grade.Using this model,the situation of seismic damage on reinforced concrete structure can be accurately identified by depicting the relationship between the two sets from all the aspects of the same-contrary-indefinite characteristics.This method was verified clearly through the practical example,and the rationality and validity were demonstrated.By this practice example,the model proved to be accurate and logical in evaluating the degree of structural seismic damage.更多还原
