Özet

In many developing countries, existing reinforced concrete (RC) buildings, which were built several decades ago, were constructed with poor quality concrete and insufficient reinforcement details. Experiencing heavy damages aftermath of earthquakes, it is clear that seismic retrofit is required to minimize losses. In this paper, the results of an experimental study on seismic performance of pre-damaged and undamaged substandard RC columns retrofitted using aramid fiber reinforced polymer (AFRP) rods are presented. The columns were tested under constant axial and reversed cyclic lateral loads in the column weak-axis direction. Based on the outcomes of the experimental study, it is observed that significant enhancement is possible in flexural strength through the proposed retrofitting method up to 4% lateral drift ratio, which is generally sufficient against seismic actions.
