Specimens used in the experiment are modelized beam-slab-column subassemblages in the vicinity of the inner column and the corner column in the R/C frame. All of them have the same sectional dimension and reinforcements. Alternating horizontal forces having 0, 26.6 or 45 degrees to the structural plane of the frame are applied to the specimens. And flexural moment in each beam of the specimens and its resultant flexural moment acting on the column were investigated under the ultimate state. The following results are obtained from the test. When frames are collapsed by the mechanism of the beam yielding under arbitrary directional horizontal force, flexural moment applying to the column is about 85-101% of resultant beam bending moment, which is calculated under the assumption that in-plane ultimate flexural moments of the beams, which are orthogonal each other, apply to a column simultaneously
