The floor acceleration amplification (FAA) reflects the amplification effect of the main structure on the ground acceleration, but the current specification and research mostly rely on historical floor records or finite element analysis results. When complex building structures are involved, the results of calculation analysis and actual earthquake damage are often different. Based on the recorded data of the shaking table test of the scaled model of the integral structure, the FAA distribution of prototype structures along the height are obtained by fitting analysis. Using the shape model of quasi seismic response spectrum, the FAA distribution surface with a certain guarantee rate is obtained, and the corresponding calculation formulas for different structural types are proposed respectively. It can better reflect the FAA distribution characteristics of complex building structures compared with the specification. Finally, the influence of site predominant period change on FAA distribution characteristics of this type of building structure is qualitatively explored.
