Abstract
In this paper which is the continuation of the study written by the same author in Transactions of A.I.J., No. 69, Oct. 1961, when the uniform horizontal loads such us seismic fores act similarly upon each story of the symmetrical multistoried buildings of which the walled rigid frames are provided at the both ends, a paractical approximate method of finding the shearing forces carried by the middle rigid frame and walled rigid ones, which are largely given the effect of horizontal deformation of the slab, is proposed by applying the similar analytical principle and presumptions as used in the preceding paper.
