Eect of Internal and External Shear Wall Location on Strengthening Weak RC Frames

Abstract. Hundreds of thousands of Reinforced Concrete (RC) buildings have been either seriously damaged or have completely collapsed due to major earthquakes in recent years in Turkey, therefore, the construction of RC buildings gained momentum by the aid of scientic studies on strengthening. As well as mentioning the importance of the strengthening process using Shear Walls (SW) in RC buildings of poor earthquake performance, an experimental study carried out to analyze the in uence of the location of a SW on the existing system was also mentioned in this study. A total of three, two-storey, two-bay RC frames of 1/3 scale were produced for the experiments by expecting them to represent the behavior of the RC frames having weak earthquake strength; two of which were strengthened with SWs. The main aim of this study is to compare the eectiveness of internal and external SW locations on strengthened weak, RC frame earthquake behavior. The strength, stiness and ductility of the tested frames were compared within the light of numerical results obtained from the experiments. In the study, an overall comparison of strengthening methods was made in terms of applicability, usability and cost
