摘　　要：提出高层建筑框支剪力墙结构简化分析的超元法 ,即在通常的假定下 ,对上部剪力墙部分经连续化处理以后 ,简化为等效柱 ,底层框架部分在柱顶转角、侧移相等的假定下 ,视为等代柱 ,整个结构视为一个悬臂柱 ,然后按楼层划分成超级单元 ,用矩阵位移法分析。该法结构自由度很少 。The super element method is presented for analysis on tall building structure with shear walls supported by frames. After treatment of the upper shear wall with continuous technique,it can be treated as an equivalent column. The bottom frame can be treated as substitute column with the assumption of equal slopes and lateral displacements at the top joints of the bottom frame (the stiffness of the crossbeams is infinitely great). So,the whole structure can be considered as a cantilever column and is then analyzed by matrix displacement method,which is very simple in calculation.
