Define the proess of Eccentric Prestressing
In this form of prestressing, the centroid of cross-sectional areas of tendons is not located at the centroid of the cross-section. The distance between the centroid of the cross-section of the concrete member and the centre of gravity of tendons is called as the eccentricity of tendons. Due to this eccentricity, a moment, whose magnitude is equal to the product of the prestressing force and the eccentricity, is applied on the concrete cross-section.
