A comprehensive experimental campaign was conducted at METU Uğur Ersoy Structural Mechanics Laboratory to investigate the seismic response of infilled reinforced concrete frames. A total of 22 half-scaled frame tests were conducted on identical, single-story, single-bay frame specimens infilled with hollow clay bricks and aerated concrete blocks. Retrofit techniques such as isolation joints, steel mesh overlays, sliding joints and horizontal steel ties were investigated. Frame specimens under constant vertical load were subjected to cyclic in-plane, monolithic out-of-plane and simultaneous in-plane and out-of-plane loading conditions using servo controlled hydraulic jacks and airbags. Particular attention was devoted to the definition of lateral drift-based performance limits for infill walls, identification of in-plane wall damage on the out-of-plane capacity and the performance of retrofit techniques applied to infill walls to enhance earthquake resistance.
