| 摘 要： | 利用框筒结构等效连续化和弹性力学变分原理，推导了变截面高层框筒结构的应力调整函数Ｓ（ｚ），并联合运用等效筒体中的应力分量表达式，获得了典型水平荷载下的侧向位移，同时按通常的方法，亦可以方便地求得梁柱中的内力。给出的变截面高层框筒的实例说明了这一方法与空间有限元方法结果比较吻合。

| Abstract: | The stress-adjust function S(z) has been presented for frame-tube structure with the varying section using the method of the equivalent plane frames and adopting elasticity variation principle,and the lateral deflections are obtained with the stress formulations of the equivalent tube for three standard loads cases.Subsequently,the internal forces are obtained in the beams and columns conveniently as the general methods.The results of this paper are identical with the FEM method by an example of frame-tube. |
