In this study, behavior of RC structures during strong earthquake is investigated in the viewpoint of energy response for the purpose of studying on seismic damage mechanism.1. To study on behavior of energy response of structures, single degree of freedom system with various natural period and yielding force is analyzed. Damaging potential of earthquakes to structures is estimated by total input energy and damage of RC structures is evaluated both by ductility factor and by dissipated hysteretic energy.2. Relation and difference of response behavior between one mass and RC frame with beam yield mechanism is studied, by equivalent single degree of freedom system of frame with assumption of elastic first mode. And response behavior of one mass and RC frame designed considering energy response is investigated. It is found that restoring force of one mass is almost equal tothe base shear of corresponding frame, and that ductility factor of one mass and ductility factor of beam are related well.3. By the results of study, an earthquake resistant design procedure considering damage level as design limit is proposed. By this procedure, necessary yield force of buildings can be estimated using input energy spectrum without earthquake response analysis.

在这项研究中，为了研究地震损伤机制的目的，研究了强烈地震期间的RC结构的行为。1。为了研究结构的能量反应行为，分析了具有各种自然时期和屈服力的单个自由系统。通过总输入能量和RC结构的损害估算了地震对结构的破坏潜力，通过延展性因子和消散的滞后能评估。通过假设弹性第一模式的假设，研究了一个质量和RC框架与梁屈服机制之间的关系和响应行为的差异。考虑了一个质量和RC框架的响应行为，研究了一个考虑到能量响应的质量和RC框架。已经发现，一个质量的恢复力几乎是相应框架的基底剪切，而束的质量和延展性因子的延展性因子很好地相关。3。通过研究结果，提出了将损伤水平作为设计限制的抗震设计程序。通过此过程，可以使用输入能量谱估算建筑物的必要收益力，而无需地震响应分析。
