摘　　要：本文根据无剪刀分配法的基本原理，推导出变截面单跨多层对称叫架在任意荷载作用下的一般计算公式。适用于各种变截面对称刚荣及等截面则采的计算。与等截面刚架的计算相比，变截面刚采的计算只需将形常数与载常数按本文公式进行简单的修正便可，其它计算与等截面刚采完全相同。From the basic principle of the distribution method without shearing force, the paper deduced the ordinary calculation formula of variable cross-section single span multilayer symmetrical rigid frame under any imposed load. The formula adapts to the calculation of all kinde of variable cross-section single span multileyer symmetrical rigid feames as welll as uniform sections. Compared with the calculation of the uniform section, the calculation of the variable frame only needs to simply revise the deformation constant and load constant according to the formula, other calculations are the same as the uniform section rigid frame.
