An Experimental Study on the Power Spectra of Fluctuating Wind Forces |
| Abstract |
The wind force spectra, in along-wind, across-wind, and torsional moment, are examined through wind tunnel test for investigating the effect of wind directions and side ratios on the characteristic of wind force spectra. In wind tunnel test, depth/breadth ratios of models are between 0.25 and 4, and wind directions are between 0 and 90 . Height/square root of plan area ratio is 4. Urban flow condition is applied. Ultimately, investigated power spectra of wind force are expected to be used for predicting RMS acceleration considering wind directions and side ratios. |
