Noise barrier panels are often installed on the scaffoldings of building demolition works in order to cope with the environmental problem caused by noise and dust. However, these panels are difficult to remove and left even when strong wind is forecasted. A technical guideline can estimate wind load on the scaffoldings with panels. Still, the wind force distributions with various shape of scaffoldings corresponding to the demolition steps are not clear yet. Therefore, wind tunnel tests were conducted to get the wind force coefficient distributions on the panels for various steps of a building demolition work. Larger wind force coefficients were obtained with a model with an opening. The possible cause of such a large wind load was discussed.
