摘　　要：以1000MW机组火电厂主厂房新型型钢混凝土框架—钢筋混凝土分散剪力墙混合结构体系、按1/7进行缩尺的三跨三榀框排架子结构进行空间模型试验,通过锤击法测定结构的动力特性,同时根据拟动力试验中结构的位移反应,求得在不同破损阶段模型结构的动力特性,根据相似关系得出原结构的动力特性,而且通过与大容量机组火电厂主厂房其他框排架结构动力特性进行比较,证明型钢混凝土框排架混合结构体系可以在高烈度区大容量火电厂主厂房结构中进行推广应用.Considering a new type of hybrid structure system of steel reinforced concrete frame and RC dispersed shear wall for 1000MW power plant,the dynamic characteristics of a 1/7 scale model with three spans and three bays from the main building have been tested by hammering method. Meanwhile,according to the structural displacement response of pseudo-dynamic test,the dynamic characteristics of the model structure in different experiment stages were obtained,and the dynamic characteristics of the true structure were derived based on the analogical ratio. In comparison with the dynamic characteristics of other frame-bent structures,the results of this study show that the frame-bent hybrid structure system of steel reinforced concrete can be applied to large capacity power plants in highly seismic regions.
