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
