通过对9个不同结构特性的钢筋混凝土框架-核心筒结构，选用一定数量的地震波进行时程分析，研究了此类结构在地震作用下的总输入能及其在滞回耗能和阻尼耗能之间的分配规律，以及滞回耗能在构件及层间的分布规律。研究表明，随着地震动幅值的增大，滞回耗能比也随之增加；不同频谱特性的地震波对滞回耗能影响较大；刚度特征值对结构总滞回耗能影响不大，但对构件的耗能分配具有较大影响；结构滞回耗能主要集中于底层剪力墙和中部连梁处。

Elastio-plastic dynamic analyses of 9 reinforced concrete frame-core wall structures with different structural characteristics were performed under several sets of ground motions.The earthquake total input energy of the structure under ground motion,and the distribution regularity of the total input energy between hysteretic energy-dissipation and damping energy-dissspation were studied.The distribution of hysteretic energy-dissipation among shear wall,coupled beams and frames,and the distribution of hysteretic energy-dissipation along different stories were analyzed. The results showed that the hysteretic energy-dissipation increases with increase in the peak ground acceleration;the earthquake records with different spectral characteristics have a great influence on hysteretic energy-dissipation;although the total hysteretic energy-dissipation of structural members are steady,the distribution of hysteretic energy-dissipation among shear wall,coupled beams and frames depends on the structural stiffness features;the structural hysteretic energy-dissipation is concentrated in the bottom portion of shear walls and the middle part of coupled beams.
