To duplicate in-situ piezometric measurements, CADAM3D allows the user to define the uplift pressure distribution, both for normal operating and flood levels, by clicking the user-defined distribution button
Figure 133 shows an update of Figure 132 after the user has changed the uplift distribution. The user can also add different water heights for a joint as many times as required. In addition, by selecting one of the water heights already set, the user can either remove that water height from the list or modify it. Finally, the user can only define a unique water height for a specific position (x). The values of H in the Figure represent the piezometric heights.
Note: By activating the user-defined distribution, the software will not change the uplift distribution for static and post-seismic loadings regardless of the cracked length developed.
