中文摘要：

以17个钢框架-钢筋混凝土剪力墙混合结构为样本，选取结构自振周期r和结构刚度特征值λ作为分析参数，分析它们在不同类型地震动下的地震能量反应。研究表明，混合结构体系在地震作用下总输入能的大小主要与结构的自振周期以及地震动类型有关，剪力墙与钢框架之间的刚度关系对总输入能影响不大；总输入能等效速度谱的形态受地震动类型的影响很大，同一地震动作用下，幅值与等效速度谱值之间基本能够维持线性增长的关系，但随着结构塑性发展的加剧，这种线性增长关系的离散度会变大；在结构自振周期不变化的前提下，结构的滞回耗能比以及底部剪力墙承担滞回耗能的比例都会随结构刚度比的增大而减小。

英文摘要：

Energy response analysis is carried out in 17 steel frame - reinforced concrete shear wall systems with different periods and stiffness ratios under 4 types of ground motions. It is shown that the input energy is sensitive to period＇ T and motion type and the stiffness ratio A has little influence on the input energy. Under the same ground motion, the input energy equivalent velocity is linearly increased with the peak acceleration of motion, and the linear relationship will be gradually changed with the plastic development of structure. The ratio of hysteretic energy to input energy and the ratio of hysteretic energy dissipated by bottom shear wall to hysteretic energy are decreased with the increase of stiffness ratio A when the period T of the structure is not changed.
