摘　　要：本文通过对一个内嵌式框架-摇摆墙模型进行模拟地震振动台试验,对结构的动力特性、阻尼比、位移反应和加速度反应进行测试,研究模型结构的破坏机制和抗震性能。研究表明:模型结构具有良好的整体破坏机制,与纯框架结构相比,内嵌式框架-摇摆墙结构的刚度明显加大,所承受的地震作用变大,结构延性和耗能能力显著提高。模型试验的结果对框架-摇摆墙结构的研究具有重要的参考意义。Based on the shaking table test of a frame-woke model with bulit-in rocking wall, the dynamic characteristics of the structure, damping ratio, displacement response and acceleration response are tested, and the damage mechanism and seismic performance of the model structure are studied. The results show that the model structure has good overall damage mechanism. Compared with frame structure, the stiffness of frame structure with built-in rocking wall increases significantly, the seismic actions become larger, and structural ductility and energy dissipation capacity improve significantly. The results have important reference to the study of framework model with rocking wall.
