Abstract：The joint distribution function of wind speed and direction at the site of investigated structures should be obtained before the analysis of wind-induced fatigue life of structures is performed. In this paper, joint probability distribution functions of wind speed and direction is first derived on the basis of wind datum of two weather stations near a real structure. Then effects of the different distribution functions of wind speed and direction on the wind-induced failure modes and system failure probability of the structure are studied. The analysis results show that different distribution functions of wind speed and direction could result in different failure modes for the calculation of wind-induced structural fatigue life, and furthermore have great influences on structural fatigue failure probability.
