Tendon Prestress Loads

Function

  • Define the prestress loads to be applied to the selected tendons.

  • This load cannot be used for performing analysis with materials having nonlinear properties.

 

Call

From the main manu select [Load] tab > [Type : Prestress] > [Prestress Loads] group > [Tendon Prestress]

 

Input

Load-Temp Prestress Loads-Prestress Loads-Tendon Prestress.png

Tendon Prestress Loads dialog box

 


Load Case Name

Select a load case. Click ....png to the right to add new or modify/delete previously defined Static Load Cases.

 


Load Group Name

Assign a load group in which the tendon prestress load is to be included. Click ....png to the right to add new or modify/delete previously defined Load Groups.

 


Select Tendon for Loading

Select the tendons to be applied with the prestress load. Multi-select the relevant tendons from the tendon list with the mouse and click r.png. To delete the selected tendons click l.png.

 


Stress Value

Specify the magnitude of the tendon prestress. The prestressing location(s) may be either or both the beginning or/and end of the tendons.

Stress : input in stress unit

Force : input in force unit

1st Jacking : When both ends are stressed, specify which end is stressed first.

Begin : Jacking Force at the beginning of the tendons

End : Jacking Force at the end of the tendons

Both : Jacking Force at both ends of the tendons

NOTE.png In case of Pre-tension load type, the 1st Jacking option of Tendon Prestress Loads will not apply. Therefore, analysis results will not be affected whichever is selected.

 


Grouting : after n stage

Define the stage at which the tendons are grouted in the ducts (sheathes). The grouting stage determines the timing of using the transformed section with the grouted tendons.

Click the Add button to include the selected tendons with prestressing loads in the tendon list. To Modify the prestressing data, select a tendon, change the data, and click the Modify button. After selecting unwanted tendons, click the Delete button to eliminate the tendons from the list.
