Özet

Tests of square short columns confined with steel straps are reported in this study. A temporary confining method that can be implemented in a short period of time with benefits of increased strength, ductility, and energy dissipation is proposed for square reinforced concrete (RC) short columns within the scope of the research. The method was based on the confining of columns with steel straps as transverse reinforcement. Twelve columns with a scale of 1/3, including three reference and nine strengthened specimens, were tested under axial monotonic loading. The longitudinal reinforcement ratios of columns and the steel strap spacing were the test parameters. The results indicated improvement in terms of strength, ductility, and energy dissipation. Consequently, this method is claimed to have the potential to be adopted for temporary strengthening of columns in the future.
