摘　　要：结合能量分析法和文献[1]提出的钢筋混凝土框架结构“三水准”地震损伤性能目标,采用改进的双参数线性组合地震损伤模型,本文提出了基于能量分析的地震损伤性能评估方法;通过算例说明了本文提出的抗震性能评估方法不仅能够准确地分析结构在大震作用下的地震损伤性能,而且思路简洁、计算方便、可用于结构抗震性能评估;另外,本文提出的地震损伤模型具有较强的灵活性,可适用于不同钢筋混凝土构件和结构的抗震性能评估。In this paper, an evaluation method of structural seismic damage performance is presented by using a seismic damage model with tow-parameter linear combination, based on the energy analysis and three-level seismic performance objectives suggested in reference. An example is shown that the evaluation method proposed in this paper can accurately analyze the structural seismic damage performance, the calculating method is easy and applicable to evaluation of the structural seismic damage performance. The seismic damage model suggested in this paper can flexiblely apply to reinforced concrete members and structures.
