Wind loads on roofs fluctuate significantly, both across their surfaces and in time. A 1/50 scale wind tunnel study was conducted to determine the correlations of these load fluctuations on batten to truss connections. This study found that load histories between neighbouring connections are correlated and are sensitive to wind direction. Critical wind directions that cause the highest uplift loads are not necessarily those that experience the highest correlations amongst neighbouring connections. Additionally, for different wind directions loads at connections to the left, right or diagonally across from the critical connections are more correlated, suggesting that the path that a progressive failure takes is dependent on wind direction and the location on the roof where it initiates.
