Mechanical Analysis of Eggshaped Digester Tanks and Selecting Prestressing Methods/Liu Yaowu,Li Chuanping,Zhang Baohe(Shanghai Giant Prestressing Engineering Corporation Limited,Shanghai 200235,China)
Abstract:Considering eggshaped digester tanks on mechanical complexity and limit of dimensions,two different prestressing methods are presented for laying prestressing tendons on longitude,latitude and 45 degree.Based on the comparison of the two methods,a scheme of laying prestressing tendons is drawn on longitude and latitude.The scheme can satisfy the workability of eggshaped digester tanks on different working conditions and the requirements of construction.
Keywords:eggshaped digester tanks; prestressing tendon; mechanical analysis
