| Abstract |
This study aims at proposing an empirical equation of the across-wind fluctuating moment and spectral density coefficient as a function of the side ratios of buildings. In order to estimate empirical formula, wind tunnel tests have been conducted on aero-elastic model of rectangular prisms with various breadth-to-depth and side ratios in turbulent boundary layer flows. In this paper, criteria of across-wind fluctuating force and spectral density are briefly discussed and then these results were mainly analyzed as a function of the side ratios of buildings. Finally, approximate equation for the across-wind fluctuating moment and spectral density coefficient were proposed. |
