Abstract

In the preliminary design stage of a building, the wind load is generally calculated through a given criteria and applied to the wind resistance design. However, the wind load calculation formula provided by KDS-2022 can be calculated for various side ratios(D/B) and Aspect ratios(H/${\sqrt{BD}}$), but only for one wind direction (0°) of a rectangular structure can be calculated. Therefore, it is not possible to fully consider the wind load generated in the wind direction other than 0°. In this study, the wind force coefficient required to calculate the wind load tended to change according to various Aspect ratios(H/${\sqrt{BD}}$), side ratios(D/B), and surface roughness. The experiment was conducted by setting variables with four Aspect ratios(H/${\sqrt{BD}}$), 11 side ratios(D/B), and four surface roughness. In the case of the mean wind force coefficients of the X-axis and Y-axis, the effect of the Aspect ratios(H/${\sqrt{BD}}$) was small, and the fluctuating moment coefficient was found to be affected by all of the Aspect ratios(H/${\sqrt{BD}}$), side ratios(D/B), and surface roughness. In the case of the Z-axis, it was found to be affected by the surface roughness and side ratios(D/B).
