The purpose of this study is to calculate wind force coefficients for the design of signboards in Korea. The need of a study on drag force coefficients of the signboard has been recognized for many years. The high frequency force balance test was conducted on 5 types of signboard models at Kumoh National Institute of Technology. Drag force coefficients with various aspect
ratios(B/C) 0.5, 1, 2 and clearance ratios(C/H) 0.5, 0.7, 0.9 are tested for 0° wind direction. Then, we compared experiment data with ASCE and Letchford's design data. The results of this study is 18% less value than Letchford's design data.
