Özet
In this paper, the effects of structural damage on the modal characteristics of a substandard full-scale reinforced concrete (RC) building were investigated. The RC building was a representative of large number of existing substandard RC buildings. The building was subjected to different levels of structural damage through quasi-static reversed cyclic lateral loading. Ambient vibration tests were carried out not only before and after quasi-static lateral loading cycles, but also at a certain damage level. The vibration test survey showed that modal frequencies decreased while damping ratios increased with the increasing levels of damage. More importantly, since the structural damage pattern due to quasi-static cyclic lateral loading was similar to ones observed in existing RC structures after earthquakes, determining the changes in dynamic characteristics at different levels of structural damage can be useful for estimating the residual performance of the structure after an earthquake.
