The purpose of this study is to grasp influences of multi-story mullion-type walls on behavior of RC structure frame analytically. A fiber-model is applied to the mullion-type walls, and 1 span multi-story RC frame structures which have the multi-story mullion-type walls and which are designed without regarding ones as structual elements are analized with push-over method. The conclusions are as follows. Mullion-type walls can raise horizontal load-carrying capacity, but there is possibility of story-collapse at lower story in the case of a structure with many stories. The mullion-type walls may affect upper structural elements because of the accumulation of the axial elongations of the mullion-type walls. Axial elongations of the mullion-type walls whitch exsist in a lower story are suppressed, so that, some additional axial force ratios of ones rise to more than 0.3-0.4.
