Abstract The design of the buildings to the earthquakes is a very critical issue. Some of existing reinforced concrete buildings does not have sufficient performance in terms of earthquake. These buildings must be demolished or strengthened. Strengthening design is not a simple engineering account but requires deep knowledge of composite material behaviour. In this study, the structural advantages and disadvantages of various strengthening types of reinforced concrete beams are investigated. In the analyses, the reinforced concrete jacketing increased the bending and shear strength of the existing beam but the difficulty of this application was found to make it difficult for such designers to be preferred in beams. Also, the addition of new reinforced concrete section to be added to the lower zone of the beam has also contributed to the bending capacity by increasing the useful height of the beam. Keywords: Beam, strengthening, design, earthquake. * ADDRESS FOR CORRESPONDENCE: Musa Hakan Arslan, Civil Engineering Department, Konya Technical University, Kampus, 42250 Konya, Turkey.
