摘　　要：对1 7大型火力发电厂三跨三榀钢筋混凝土横向框排架子空间模型,分别用激振法和柔度矩阵法进行模型结构动力特性试验,研究该结构的前三阶周期和振型,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,最后根据相似关系得出原型结构的动力特性。Considering the characteristic of main R C building in large-scale thermal power plants, a 1/7 scale model of three spans and the main building with three bays have been tested by man-excitation and measurement of flexibility matrix to determine dynamic property of the model. According to the pseudo-dynamic test results, the frequencies of the model at different experiment stages are obtained. At last, the dynamic property of the original structure is obtained based on model similarity theory.
