Abstract
The purpose of in this experimental study is to investigate the effects of short column behavior due to window opening at two strengthening methods. At this study, seven reinforced concrete frames as two stories, 1/5 scaled and one bay were produced. The specimens contained several deficiencies that were commonly observed in residential buildings in Turkey. These specimens were tested under lateral loading and constant vertical loading. First specimen was produced as the reference bare frame. Second and third specimens were produced with infill autoclaved aerated concrete blocks wall. Fourth and fifth specimens were strengthened with infill RC shear wall. Sixth and seventh specimens were strengthened with external RC shear wall and RC column jackets. The walls of all specimens were manufactured with two different windows opening to investigate the effects of short column behavior. The test results showed that these applied strengthening methods have significantly increased the lateral load carrying and energy dissipation capacities, initial stiffness of the RC frame. Thanks to RC column jackets, at specimens with the external RC shear wall was prevented to the short column behavior.
