Abstract

Abstract

The system of full-frame-supported high-rise building structure with thick plate transfer has been gradually applied in the subway superstructure property development, in order to explore the influence of changes in the eccentricity of the center of mass caused by vertical retraction of upper multi-tower structure on the full-frame-supported structure with thick plate transfer, the paper designed a 1∶35 scale full-frame-supported multi-tower structure with thick plate transfer, the eccentvicity of the center of mass was calculated, the shaking table test was carried out, and seven finite element models were established to analyze the overall eccentricity parameters combined with ETABS. The results showed that the overall eccentricity of the structure would be changed due to the vertical retraction of the full-frame-supported structure with thick plate transfer, and the acceleration response of the structure increased with the increase of the eccentricity of the center of mass of the structure. At the same time, the experimental and numerical results showed that the torsion effect of the full-frame-supported structure with thick transfer increased with the increase of the overall eccentricity E, which effectively verified the experimental results.
