M. To add a prestress or post-tension load to members
To add a load due to prestressing or post-tensioning to members, use the following procedure.
Tip: This will add the load item to the currently selected load group selected in the program status bar.
Select the loading
- Type the prestress Force (in current units).
- Type the Eccentricity Distances used to control the tendon profile at the Start, Middle, and End of the member. Eccentricities are measured in the local y axis (i.e., positive is "up" with respect to the local y axis). The cable profile is assumed to be parabolic (i.e, a "draped" tendon profile). Refer to G.15.5 Prestress and Poststress Member Load for further details on how the tendon profile shape is calculated.
- Click Add. The load item is added to the selected load case.
