| 摘 要： | 高层建筑物设计通常是把上部结构和地基基础分开来进行计算分析,这种不符合实际的假定必定会带来结果的偏差.因此有必要考虑彼此间的耦合作用,文中对多高层建筑上部结构和地基基础共同作用的差状态进行研究.在考虑钢筋混凝土框架高层建筑上部结构和地基基础共同作用情况下,对差异衰减理论进行讨论:求得连分式衰减理论中实矩阵的矩阵特征值、特征向量,进一步对沉降模式进行分析.之后结合上部结构的变形规律,尝试给出一种基于此规律的适合于工程实际应用的计算方法. |
| 关 键 词： | 钢筋混凝土框架结构 共同作用 差异衰减 线性叠加法 正交性 |

| Abstract: | In practical design,the upper structure and the foundation of a high-rise building are generally handled in separate ways.As a result of such mal-practice,errors may easily occur,and this naturally necesitates a consideration of the coupling between them.This paper presented a study aimed to deal with such subtract state in interaction of the two so as to obtain the eigenvalue as well asthe eigenvector of the real matrix by continued fraction attenuation theory.The deformation model and the distortions are also analyzed in trying to bring about a practical calculation method. |
| Keywords: | RC frame interaction attenuation method of linear superposition uprightness. |
