Downstream rotation point
Damage to the upstream face, mainly due to thermal effects, can lead to damage at a depth that varies with temperature fluctuations. In this case, the user can define a rotation point other than the downstream point of the foundation by using the window shown in Figure 43. This dialogue box is activated by the Downstream Rotation Point command in the main chute window. This rotation point is used exclusively to evaluate the downstream overturning safety factor.
