Abstract

Considering the acceleration effect of sloping terrain on wind field, the wind load characteristics of single column three-sided billboard under sloping terrain are studied based on CFD numerical simulation and fluid-solid coupling method. Firstly, the flow field and surface wind pressure characteristics of the billboard at different slopes &#xF061;, slope top position x and wind angle θ were discussed, then the load increase factor IC was proposed as a quantitative indicator of wind damage, and finally wind resistant installation suggestions were given. The results show that the numerical calculations can be used for load characteristic studies. As &#xF061; increases, the positive pressure extremes in panel 1-A gradually increase, and the reattachment capacity of the separated airflow in panels 2-A and 3-A decreases, resulting in an enhanced net wind pressure superposition effect on the panels. And the studied α in 45° has the most significant effect on load increase, therefore three types of wind resistance zoning are proposed, billboard installation should avoid class I (0≤x<1H), where IC>1.7. In addition θ = 60° can reduce panel skin damage and overall instability probability, θ = 30° should be avoided to reduce support structure buckling damage.
