Tendon Load

The Tendon load definitions are a series of prestressing cable stressing actions at their ends. For each side, the PT cables (Tendons) can be:

1. PRE: prestressed, stressing;
2. REL: releasing;
3. SWED/DEVL: length of wedge or development slip:

These Tendon load actions input can be from each side, i.e.:

• L - Left side, or;
• R - Right side.

Also, the input actions values can be represented by:

• a total force (kN), or;
• a factor of SIGP, i.e., a ratio of the force.

The final instant action results for a tendon can be visualized in the Normal force diagram button, as shown below.

Stress actions are generally grouped by stress labels that allow for common definitions. The Tendon Load definition is combined with the action Stress in the Schedule Actions and the Tendon geometry defined in Structure > Tendon data and properties to create immediate losses. The total losses need additional Creep & shrinkage calculations and can be derived from final summation loads.
