摘　　要：用同一个单层钢框架结构模型,分别做成传统结构体系和楼板隔震消能结构体系。模型在每一种结构体系下分别做模拟地震振动台试验,先后在x向按7度小震和大震烈度输入E l Centro波、Taft波和天津波,比较单层钢框架模型在两种结构体系下的地震反应。试验结果表明,采用楼板隔震消能结构体系能够显著减小结构的加速度反应和底部剪力反应。To investigate the seismic behavior of the steel frame model has been made into the traditional slab isolating and energy dissipating （SLED） structure, one structural system and the SIED system, respectively. Shaking table test was performed for the frame model in each of the two structural systems. E1 Centro, Taft and Tianjin ground motions, tuned into minor and severe intensity of 7 degree, have been input to the table, respectively, to in- vestigate the seismic responses of the model. The test result shows that the acceleration and base shear responses of the model have been remarkably reduced when using the SIED structural system.
