This paper presents the series of experimental tests of reinforced-concrete (R/C) frame structures infilled with solid brick wall and opening brick walls to evaluate contributions of brick infills with openings to lateral strength of RC frames. Four 1/4-scale single story and single bay RC frame specimens, one bare frame and three infilled frames, were tested by applying the static monotonic lateral load to the upper beam of specimens. During the testing, lateral displacements of infilled structure were monitored to control the incremental lateral loads. The cracks, crack propagation and major cracks were observed throughout the tests to identify the mechanism failure of specimens. As the results, failure of brick wall was prior to the failure of RC columns. The lateral strength and stiffness of infilled frames were always higher than those of bare frame. The solid brick infill significantly increases the lateral strength of overall RC frame more than two times. The brick infill with a center opening of size 40% and the brick infill with 2 (two) openings of size 25% increase the lateral strength of R/C frame by about 25% and 47%, respectively.
