变截面高层框筒结构内力和位移简化计算方法

Simplified Analysis of the Internal Forces and Lateral Deflections in Frame-tube Structure with the Varying Section

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．

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.
