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。Based on Set Pair Analysis （SPA） theory, Set Pair Analysis Model （SPAM） is established in seismic damage evaluation on reinforced concrete structure, which took intemal 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 structmal seismic damage can be calculated from the objective and sub- jective evaluations. Four different types of structure is analyzed on the model, that the evaluation result is rea- sonable, fine and high resolution. By this practical example, the model proved to be effective in seismic damage evaluation on reinforced concrete structure.
