摘　　要：本文从变截面杆件出发,导出框架节点转角及侧移方程。再将侧移消除,使之仅有转角,并求出分配系数,从而得无侧移分配法。此法可用于多层多跨框架的分析,为只适用于单跨的无剪力分配法的一个推广。然后进一步考虑杆件的刚域及剪切变形,则可以分析框-剪结构及壁式框架。This paper presents a method for analyzing multistoried frame, for which the equations of joint angular rotations and sidesways of frame with varying cross section members have been first derived. The distribution factors are then obtained by eliminating the sidesways and with the angular rotations remaining in the equations. The method may be called the 'no-sidesway angular displacement distribution method' and can be used to analyze multistoried and multispanned frames. It can also be extended to the application of no-shear moment distribution method for solving single span problems to mullispan ones and for analyzing frame-wall structures or wall type frames in consideration of the effects of rigid region and shearing deformation of members.
