In this paper, free vibrations of symmetrical-three-bay frames are discussed as an application of the fundamental theory (Part 1), which had dealt with approximate analysis of multi-storey frames as bar-like structures in consideration of warping deformation. And also included here is a procedure for the case where the non-uniform structure is represented by a series of unifom sections, considering the application to actual design of structures. As an example, as a result of analysis of frames with shear wall, it has been shown that the warping deformation has a great influence on the natural frequences, the deformation and the stress distribution of structures. The results reported here suggest the necessity taking account of the warping deformation in structural design, especially in case of wall-frame structures. Furthermore, it has also been shown that the restriction of warping at the top or the middle height has an effect on the decrement of the deformation, and that the influence on the stress distribution of upper structure due to the deformation of the foundation is not negligible. The structural model proposed by present writers may be useful not only for static but for dynamic analysis of tall shearwall structures in preliminary design.
