This study aims to estimate the wind loads acting on a tower structure by comparing and reviewing design codes and the results of wind tunnel tests. To this end, the modal properties of the tower were identified through short-term on-site measurements of the Busan Tower in Korea. -e wind load acting on the tower was calculated using four design codes: KBC2009 (Korea), ASCE7-10 (USA), EUROCODE (Europe), and AIJ2004 (Japan). Additionally, force measurement tests and aeroelastic model tests were conducted for comparison. -e results obtained indicated that the design wind velocity of each design code differed slightly, reflecting the individual characteristics of each country. -e base shear force, base moment, and maximum displacement obtained from each design code were similar to those obtained in the wind tunnel tests.-emagnitudes of the base moments and maximum displacements calculated by each design code were in the order of KBC > AIJ ≈EUROCODE > ASCE7. -e overall results indicate that each design code reasonably estimates the wind forces and the responses of the tower and also has an appropriate safety margin. -e scatter in the predicted wind loads occurs primarily from the variations in the design wind velocity in the respective design codes.
