It is very important to access the damping ratio accurately in the wind design of tall buildings, but the damping ratio is not specified in the Korean Building Codes and thereby the values provided in foreign codes are adopted somewhat arbitrarily by engineers. The significant portion of concrete tall buildings in Korea has the shear wall structure system, and residential buildings have larger gravity load than buildings in other countries due to the use of floor heating system. Therefore, the damping ratio provided in foreign codes may not be directly applied to design of tall buildings in Korea. In this study, the damping ratio of actually built concrete buildings are measured and compared to those provided in foreign codes. It was found that damping ratio of tall concrete buildings decreases as the height of the buildings increases and the measured values are significantly smaller than 2.0% of the ASCE code.
