摘　　要：概要介绍了多自由度结构能量分析方法,根据单自由度体系得到的输入能量谱,研究分析了多自由度与单自由度输入能量和耗能的等效性问题,并对一座钢筋混凝土框架结构算例进行了能量计算,对计算结果进行了分析,为能量分析设计方法应用于结构抗震设计进行有益的探索。In this paper, the energy analyzing methods of MDOF system are briefly presented. According to the structural energy design response spectrum obtained from the SDOF system, whether the problems of input energy and dissipation energy of SDOF system are equivalent to those of MDOF system are studied. Then, all kinds of energy of a reinforced concrete structure are calculated and the results of calculation are analyzed to create conditions for design methods of structures based on energy concept.
