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. </span> </p> <p> </p>}, number={1}, publisher={Igdir University}
