Abstract
Prestressing tendons in the wall of circular storage tank are investigated from the viewpoint of equivalent load method. Special attention is paid to the effectiveness of eccentricities of the hoop and vertical tendons. Local effect at the bent Point of vertical tendon in the wall with varying thickness is examined. Some aspects which are frequently overlooked or misinterpreted in the conventional analyses of vertical tendons are discussed. Numerical examples are presented to emphasize the significance of accurate analysis of the vortical tendon in practice. It is expected that the equivalent load method can be effectively used to simplify the analysis of tendons in the circular wall and to minimize the errors.
