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( ) and
Aspect ratios( ), 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( ), side ratios( ), and surface roughness. The experiment was
conducted by setting variables with four Aspect ratios( ), 11 side ratios( ), 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( ) was small, and the fluctuating moment coefficient
was found to be affected by all of the Aspect ratios( ), side ratios( ), and surface roughness. In the case of the Z-axis, it was
found to be affected by the surface roughness and side ratios( ). |
