摘　　要：【目的】研究板式转换层对高层建筑结构抗震性能的影响。【方法】利用ANSYS通过对比分析高层建筑在等效侧向刚度影响下的自振周期、层间位移、层间位移角,来研究板式转换层结构的抗震性能。【结果】自振周期可以用来判别结构的刚度和稳定性,低阶振型对结构起主导作用;转换层下部结构及上部结构的等效侧向刚度比与落地剪力墙厚度呈线性正相关。【结论】在结构设计中可以通过调整落地剪力墙的厚度,找到最为合理的等效侧向刚度比,提高结构的抗震性能,在设计时要重点考虑。[Purposes]This paper aims to investigate the influence of panel transfer layer on the seismic performance of the structure of high-rise buildings.[Methods]This paper uses ANSYS for comparative analysis of the effects of equivalent lateral stiffness on the natural frequency,inter-story displacement,and inter-story drift of high-rise buildings to investigate the seismic performance of the panel transfer layer.[Findings]The natural frequency can be used to assess the stiffness and stability of structures,with lower mode shapes playing a dominant role.The ratio of equivalent lateral stiffness between the lower and upper structures of the transfer level is linearly positively correlated with the thickness of the shear walls at the ground level.[Conclusions]In structural design,adjusting the thickness of the ground-level shear walls can help find the most reasonable ratio of equivalent lateral stiffness,thus enhancing the seismic performance of the structure,which should be a key consideration during the design phase.
