Abstract
In the previous paper, the continuous vibratory systems, such as the cantilever shear beams, were devised as the vibratory models of muttistory buildings so that their masses were uniformly distributed along the height and the lateral shearing ridigities were variant. Then, They had only one element of dynamic character, say "compound value of mass and ridigity". Observing the graphs of the compound values distribution of the 21 practical examples in the above paper, some assumptions of mathematical functions which are similar to them might be obtained, and the characteristic equations of the cantilever beams can be solved through introduction of these functions. These trials are studied in this paper. Comparing the natural periods and the shape functions of the equivalent cantilever beams with these of some practical examples of multistory buildings respectively, similarity between them seems satisfactory, especially so in the case of simply shaped buildings.
