摘　　要：巨型结构体系是适应高层及超高层建筑发展而出现的一种新型结构体系,但目前针对巨型框架结构的相关研究较少,为了较好地研究巨型框架结构的抗震性能,按照我国工程设计规范设计了一个55层39 m×36 m×201 m高超高层巨型钢筋混凝土框架结构(7度设防、Ⅱ类场地),以此作为振动台试验原型结构,设计制作1/25的缩尺整体结构模型进行振动台试验。主要介绍了该试验模型材料的选择、动力相关系数的设计及试验方案的设计,为今后相关类型的试验提供一定的参考。The mega-frame structure system is a new type of structural system to adapt to the development of high-rise and super high-rise buildings. However, there is less study on the mega-frame structure currently. In order to study the seismic performance of the mega-frame better, according to Chinese Engineering Design Standard, a 55 layer 39m×36m×201m super high-level reinforced concrete mega-frame structure was designed in a region with 7 seismic fortification and II site. Which was used as the scaled integral structure model of shaking table test for earthquake simulation. In order to study the seismic performance of the mega-frame better, it was described the choosing of materials for the test model, the design of the dynamic correlation coefficient and the design of the test program, which provided a reference for future related experimental design.
