This report describes wind pressures acting on prestressed concrete egg-shaped digestion tanks in various arrangement. Egg-shaped digestion tanks are the sludge digestion facilities in sewage treatment plants and have been widely constructed in Japan since 1980's. After the passing of the typhoon T9719, the cladding of the tank in Miyazaki City was damaged. Therefore, the wind tunnel tests were conducted to clarify the reasons of the damage and to evaluate the design load of the cladding for the future construction. The results of the wind tunnel tests are reported in this paper.
