【摘要】 基于集对分析理论,选取整体损伤指数、最大层间位移角、滞回耗能循环次数和楼层能量集中指数作为评价指标,建立了钢混结构地震损伤评价的多元联系数集对分析模型。模型将多指标表示成一个能从总体上衡量损伤级别的n元联系数,用层次分析法确定指标权重,从主客观两方面定量计算地震损伤程度。将模型应用于对4种不同型式的结构进行分析,该评价模型严谨,评价结果合理、分辨率高,是钢混结构地震损伤评价的有效方法。更多还原

【Abstract】 Based on Set Pair Analysis(SPA) theory,Set Pair Analysis Model(SPAM) is established in 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.All Indexes can be summarized into n-member connection number.Analytic Hierarchy Process(AHP) is applied to calculate the weighing values so the degree of structural seismic damage can be calculated from the objective and subjective evaluations.Four different types of structure is analyzed on the model,that the evaluation result is reasonable,fine and high resolution.By this practical example,the model proved to be effective in seismic damage evaluation on reinforced concrete structure.更多还原
