Strengthening of structures may become a necessity to overcome the mistakes made during the design and construction phases of existing reinforced concrete (RC) buildings. In recent years, researches have been intensified on the economical and easy application of the strengthening of masonry infill walls in RC buildings. Strengthening of masonry infill wall with steel reinforcing mesh and additional mortar layer, fiber reinforced polymers and prefabricated concrete panels have become in the forefront of these techniques. In this study, the RC frame infilled with masonry walls and strengthened with steel reinforcing mesh and mortar layer was examined experimentally. One of the most important reasons for choosing this method is that the strengthening could be achieved with less cost, workmanship and without the need to prepare molds for reinforcement. The main variables that have been examined in the current study are: the anchorage length, spacing, and configuration which were applied to the frame and infill wall and the added layer are on the inside or outside wall. A total of 11 specimen, 1/3 scale, one-bay, one-story nonductile RC frames with masonry infill wall which representing the deficiency in the existence building by using low-compressive concrete, insufficient stirrups, and strong beam in comparison to column were constructed and tested under the effect of repeated seismic load. Load-displacement behaviors, initial stiffness, displacement ductility rates, and energy consumption capacities are interpreted.
