This paper reports the test results of two 1/4 scale 3-story shear wall specimens subjected to cyclic loadings. One of the specimen had diagonally aligned openings and the other had vertically aligned openings. The displacements of the beams around the openings were measured using digital cameras. The deformations obtained at the intermediate floors of the specimen with vertically aligned openings, which showed the most brittle behavior, were concentrated in the areas between the openings. Those of the specimen with diagonally aligned openings, with more ductile behavior, were widely distributed.
