With the rapid developing of large outdoor billboards in recent years, the double-plates billboard is destroyed by strong wind occasionally. Wind tunnel test is conducted to study the wind pressure characteristics of the kind of open-plate structure. The statistical characteristics of net pressure distribution on the plates in different wind directions is comprehensively analyzed. The distribution of pressure coefficients on the plates are given. Non-Gaussian features on local regions are studied, and the extreme pressure are calculated using Hermit moment method as well. Wind pressure regions and the corresponding design parameters are given.
This study may provide basic data and analysis for wind resistant design of the double-plates billboard.
