Experimental Study of RC Frame Infilled with Opening Brick Wall

—A total of three reinforced concrete bare frames infilled with brick walls were cyclically tested in this study. Each frame was infilled with a different shape of brick wall. A cyclically loading test was conducted for each specimen so that the hysteretic behaviors as well as the evolution of the failure mode of each specimen can be revealed, especially for the different shape of the infilled brick wall. In fact, the hysteretic behaviors of each specimen can be disclosed by examining the variations of the hysteretic loops of lateral forces-lateral displacement relationships while the evolution of the failure mode of each specimen can be manifested from the test procedure. There was no short column failure of the side column for each specimen although it was constrained by the infilled brick wall. It is affirmed that the stair-step crack pattern is generally consistent with the diagonal force transfer mechanism of brick walls.
