[提要]  为进一步研究巨型框架结构的抗震性能，探讨巨型框架结构的抗震设计方法，以具体应用工程为背景，制作了两个缩比为1:6的巨型框架局部模型，进行了低周反复加载试验。结果表明，钢筋混凝土巨型框架结构具有良好的抗震性能，采用钢骨混凝土能够增加巨型框架结构的延性，采用八字型偏心支撑节点能够达到提高巨型框架结构耗能能力和延性的目的。

In order to study the aseismic behavior and design method of mega-frame structures, two partial mega-frame models have been made.  According to practical engineering, the scale of the model is l:6. Then a low-cycled reverse loading experiment for the mega-frame models was proceeded. The results verify that the reinforced concrete performs good behavior of aseismic ability and the steel reinforced concrete can enhance displacement ductility. The energy dissipation joint can enhance mega-frame's energy dissipation ability and displacement ductility.
