Walls are the main carrying units of masonry buildings. They have certain advantages, like being economical and easily constructed. Therefore, many experimental studies have been performed. In this study, walls produced from aerated concrete (AC) and hollow brick (HB) strengthened with steel fiber-reinforced concrete panels were tested. Eighteen of 24 walls were strengthened with concrete panels that were produced by using steel fibers at certain ratios. The other six ones were reference specimens. The results obtained were expressed as mean values. The strengthening method significantly increased energy consumption capacities and shear strengths.
