    An experimental study on the seismic performance improvement of nonductile reinforced concrete structures with external shearwall application
    (CRC PRESS-TAYLOR & FRANCIS GROUP, 2015) Bahadir, F.; Balik, F. S.; Korkmaz, H. H.; Kamanh, M.; Unal, A.
    Turkey lies over one of the most active seismic zones in the world. Several destructive earthquakes resulted in high dead losses in the last century. This shows that the residental buildings with poor earthquake resistance must be rehabilitated with rapid, economical, feasible, functional and effective strengthening methods. In this study, six reinforced concrete frames with one bay-two storeys and in 1/3 scale were tested. The specimens contained several deficiencies that were commonly observed in residential buildings in Turkey. The applied lateral loading was reversed cyclic loading that simulates the earthquake exicitions. First specimen was the reference specimen and didn't contain any strengthening. The other specimens were strengthened with external RC shear walls with or without window openings. The size and position of the openings are parameters in the study. Columns of the frames also jacketed with reinforced concrete. The hysteresis curves and envelope curves were presented within the paper. In the conclusion, the capacity increase of the frame was discussed and several recommendations were presented. Test results showed that external shear walls significantly improved the lateral load carrying capacity, stiffuess and energy dissipation capacity of the bare frame.
