摘　　要：将高层建筑框架结构与其基础等效连续化为一个半无限大弹性地基上的闭口薄壁筒体,并以此三维模型,用半解析法分析计算了受静力作用的高层建筑框架结构与其基础、地基的共同工作.通过算例分析,得出了一些很有价值的结论.In the paper,the superstructure and its foundation of a tall building frame structure are simplified equivalently and continuously to a three-dimensional model,which is a combination of thin-wall tubes on semi-infinite elastic subgrade.And the interactions between these three are computed and analyzed with the three-dimensional model by semi-analytical approach based on ODE（Ordinary Differential Equation） Solver,the effectiveness of which is verified through a numerical example.Some valuable conclusions are obtained.
