Abstract: Taking a shearing force wall structure of 12 floors RC frame as an example,this research was carried out by virtue of ANSYS-a software of the finite element,which was adopted to analyze the internal force and the distortion of the superstructure in the cases of "the pile-soil-superstructure common coupling reaction" and "the normal design conditions",and then the results ware compared with each other.The final result indicates that the influence of the substructure to the superstructure should be fully taken into consideration in designing a structure of the high-rise building,in order to make the design more reasonable.

Key words: high-rise building, pile-soil-superstructure, coupling reaction, internal force, displacement, contrast analysis

摘要： 以某12层钢筋混凝土框架剪力墙结构为例,采用有限元软件ANSYS分析了"桩-土-上部结构共同耦合作用"与"正常设计条件"两种情况下,上部结构的内力及变形情况,并将计算结果进行对比分析。分析结果表明在高层建筑结构设计时,应该充分考虑到下部结构对上部结构的影响,从而使设计更加合理。
