Abstract:
The characteristics of flow around Y-shape prisms under various wind directions and its wind loading were studied by means of wind tunnel test. The results show that as the wind is along one leg of the model, the vibrations which are mainly caused by turbulence of oncoming flow are weak, and as the wind is along the angular bisector of two legs, the vibrations induced by vortex are strong. Increasing turbulence intensity in oncoming flow will cause both fluctuating lift and drag forces to increase significa...
