This paper is the last report of the shearing tests of reinforced concrete models, and gives the following results concerning the head title. 1. Cracking patterns for all models are shown in figures, and the modes of failure are explained. 2. Relations between the shearing deformation and the rate of shearing force to ultimate shearing load are shown in figures, and it is indicated that if the openings are not large (opening factor ξ<2/3), these relations are nearly equal to the relation in the case of wall without opening. 3. Ultimate shearing loads positive and negative load tests are shown in a plate, and it is indicated that unless the openings are very unsymetrical to horizontal and vartical center lines of walls or have extreme slit shapes, the ultimate shearing loads are given only by the function of opening factor ξ, and the effects of the situations of openings can be neglected.
