摘　　要：提出空间框架—十字交叉基础梁与弹性地基相互作用简化分析的超元法 ,即将空间框架和十字交叉基础梁简化处理为十字交叉剪—弯梁 ,按柱距划分为超级单元 ,用有限元分析与不同弹性地基相互作用问题 ,计算简便 。A super element method used to analyze the interaction of a space multistory frame structure grillage foundation beams on elastic foundation is presented. The space multistory frame structure and grillage foundation beams are treated as grillage shear bending beams, and are divided into super element according to the columns span. Then, the interaction problems of the shear bending beams on various elastic foundation are analyzed by finite element. The method presented in this paper is simpler in calculation and can be used more widely.

关 键 词：弹性地基 空间框架结构 十字交叉基础梁 相互作用 超元法
