Earthquake simulation tests of reinforced concrete (R/C) wall-frame structures were carried out to examine the effect of rocking or uplifting of wall foundation on seismic behavior of the structures. The specimens were 1/3-scale models of 6-story R/C buildings, consisted of two one-bay moment-resisting frames and one multi-story wall in the shaking direction. Tests of two specimens were carried out; wall foundation was fixed to the base in Frame A, and Frame B had a device idealizing rocking or uplifting of wall foundation. Observed maximum base shear in Frame B was comparable to that in Frame A, and maximum roof displacement in Frame B was about 1.5 times as large as that in Frame A under the same input table motion. The ratio of maximum shear in the wall to the maximum 1st story shear was more than 70%, less than 50%, in Frame A and Frame B, respectively.
