Fig. 4.10. Rectangular beams without a notch at a support (a) and with a notch on the opposite side to the support (b).

(b) For a beam notched on the opposite side to the support (as shown in Figure 4.10b):

(c) For a beam with a notch on the same side as the support (as shown in Figure 4.11):

In the above cases,

Vd is the design shear force acting on the beam. In determining the design shear force, the contribution made by any loading acting on the top face of the beam without a notch and within a distance of h from the edge of the support may be ignored due to the effect of the bearing stress (Figure 4.10a). This also applies
