Abstract
In this experimental study; five RC frames with a scale of 1/5, single spans and two storey were produced so as to reflect the characteristics of existing structures. Two RC frames were used as the reference specimens that without an infill wall and autoclaved aerated concrete blocks (AAC) infilled wall. Three of these RC frames were strengthened as CFS (Cold Formed Steel) drywall system, infill RC shear wall and both external RC shear wall and column jacketing. All specimens produced were tested under reverse cyclic lateral loading and constant vertical loading. Strength, stiffness and energy dissipation capacities of all test specimens are compared with each other. The lateral load carrying capacity and energy dissipation capacities of strengthened specimens have occurred higher than reference specimens. But initial stiffness and stiffness at the max lateral load of specimen strengthened with CFS drywall system have occurred lower than reference specimen with AACW.
