| Abstract |
The wind pressure characteristics of open large-span roofs under various boundary layer flow variations were investigated based on wind
tunnel tests, and a peak pressure coefficient model was derived for cladding design. First, the characteristics of wind pressure under smooth
flow and various turbulent boundary layer flows were analyzed in detail. It was found that the wind loads acting on the roof increased with
the increase in turbulence intensity under various flow conditions. Then the changes in peak pressure coefficients were carefully checked with
variations in turbulence intensity, and comparisons were made with the proposed values from previous study. Finally, based on turbulence
intensity, a model for peak pressure coefficients was proposed, it can be applied to the cladding design of open large-span roofs. |
