Analysis of Frames: No sidesway The slope-deflection method can also be used for the analysis of frames. Since the axial deformations of the members of frames composed of common engineering materials are generally much smaller than the bending deformations, the axial deformations of members are neglected in the analysis, and the members are assumed to be inextensible (i.e., they cannot undergo any axial elongation or shortening).

Analysis of Frames: No sidesway No sidesway will occur in an unrestrained frame provided it is symmetric with respect to both loading and geometry as shown in figure. The same general procedure as for continuous beams.
