Webdesigner looks at the prestressing steel as a cable applying loads to the con-crete. The prestress is represented as a system of equivalent vertical loads along the beam length (Figs. 2a and 2b), and as concentrated moments at the supports (Fig. 2c). The equivalent forces on the beam cause a shear in the concrete. The shear diagram for the ...
