Section Type
1 Cell
No interior web is present.
2 Cell
A single interior web partitions the PSC box.
H1, H2, H3...
Referring to the guide diagram, enter the tendon locations and spacings.
Web Tendon
Referring to the guide diagram, enter the positions and spacings of the top tendons located within the width of the web.
Tendon Number
Enter the number of tendons in various positions. "Unequal" may be selected to specify irregular tendon placements - top tendons over each pier and bottom tendons in each span.
N7 and N8 represent the numbers of tendons placed in the FSM zone.
Anchorage Position
Define the anchorage position of the bottom tendons in the segments.
x
Anchorage distance relative to the segment length (refer to the diagram)
Anchorage Position is defined to consider the anchorage of tendons installed inside for PSM (Precast Segment Method).
Top Tendon Grouting
Specify the timing of grouting top tendons. Once the ducts are grouted, the transformed section properties are subsequently considered. The input signifies the timing of incorporating the transformed properties.
Prestressing step
Grouting takes place at the time of tensioning the tendons.
Every n Stage
Grouting takes place at every n stages. If n=1is entered, the grouting is assumed to take place at the next stage after the corresponding tendons are stressed. If n=2 is entered, the grouting is assumed to take place at the third stage after the two corresponding segments have been stressed.
Type 2
Tendon Tab dialog box (Type2)
Tendon and Prestress
Specify the tendon placement and magnitude of prestress. Check off the box not to consider the tendon placement.
Tendon Number...
Symmetry
Select the option for symmetrical tendon placement.
Asymmetry
Select the option for non-symmetrical tendon placement.
Unequal Data
Number of Cell : Number of Cells of PSC Box Section defined in Section tab
Position
Define the location of tendons to be placed. When 1 Cell Section with Symmetry option is selected, only one Position exists. When 1 Cell Section with Asymmetry option is selected, two positions exist. Asymmetry option will allow different tendon placements for each web, and Position 1 represents the web on the left (refer to the guide diagram).
Group
PSTG : Top slab tendon of Pier Table
PWTG : Web tendon of Pier Table
CSTG : Bottom slab tendon of interior span
CWTG : Web tendon of interior span
ASTG : Bottom slab tendon of side span
AWTG : Web tendon of side span
If Tendon Groups are defined, the tendon coordinates, stresses and prestress losses of the tendons can be verified for individual Tendon Groups. FCM Wizard automatically defines 6 Tendon Groups based on the tendon types.
Number of Tendon
Enter the number of tendons corresponding to each group. This number sets the number of rows in the tendon input table under the Tendon tab.
Tendon Group
Name of Tendon Group
Group Baseline
Referring to the guide diagram, enter the Baseline of each Tendon Group. For example, to define the tendons of PSTG (top slab tendons of the pier table), use one of the tendons of PSTG as the Baseline reference and specify Bi to enter the remaining tendons. The use of Group Baseline simplifies the input of tendons of each Tendon Group.
Tendon
Bi
The horizontal distance from the Baseline to the tendon. The left of the Baseline is considered (+) positive and the right side is considered (-) negative. If 0 is specified for the Baseline, the horizontal distance from the center of the section to the tendon is entered.
Hi
The vertical distance from the section top edge or bottom edge to the tendon
For PSTG and PWTG, the vertical distance from the section top edge to the tendon is specified.
For CSTG, CWTG, ASTG and AWTG, the vertical distance from the section bottom edge to the tendon is specified.
Anchorage
Ai
Enter the distance from the Segment end to the point of Anchorage in the longitudinal direction. Enter 0 for the Anchorage, which is located at the Segment end.
Bi
Enter the distance from the Baseline to the Anchorage across the section.
Hi
Enter the vertical distance from the section top edge or bottom edge to the Anchorage.
For PSTG and PWTG, enter the vertical distance from the section top edge to the Anchorage.
For CSTG, CWTG, ASTG and AWTG, enter the vertical distance from the section bottom edge to the Anchorage.
Ri
Enter the radius of curvature of the tendon.
Θi
Enter the slope of the tendon.
Segment
Select the Segment in which the Anchorage is included. By default, P.T. (Pier Table) is specified. If the Anchorage is located at a Segment other than P.T., select a relevant Segment. Segments in the drop-down list are automatically generated in an equal number of Segments entered in the Model tab.
FCM Anchorage
Define the Anchorage positions of the tendons in side spans. This becomes active only for the Tendon Groups (ASTG and AWTG) of side spans.
Ai
Enter the distance from the Segment end to the point of Anchorage in the longitudinal direction. Enter 0 for the Anchorage, which is located at the Segment end.
Bi
Enter the distance from the Baseline to the Anchorage across the section.
Hi
Enter the vertical distance from the section top edge or bottom edge to the Anchorage.
For PSTG and PWTG, enter the vertical distance from the section top edge to the Anchorage.
For CSTG, CWTG, ASTG and AWTG, enter the vertical distance from the section bottom end to the Anchorage.
Ri
Enter the radius of curvature of the tendon.
Θi
Enter the slope of the tendon.
Segment
Select the Segment in which the Anchorage is included. By default, P.T. (Pier Table) is specified. If the Anchorage is located at a Segment other than P.T., select a relevant Segment. Segments in the drop-down list are automatically generated in an equal number of Segments entered in the Model tab.
Tendon Property
Specify the types of the top and bottom tendons. Click the to the right of the selection field to prompt the "Tendon Property" dialog box to add or modify tendon properties.
Jacking Stress
Specify the tensioning stresses for the top and bottom tendons.
Su
Ultimate tensile strength of tendons
Sy
Yield strength of tendons
Top Tendon Grouting
Specify the timing of grouting top tendons. Once the ducts are grouted, the transformed section properties of tendon and grout are subsequently considered. The input signifies the timing of incorporating the transformed properties.
Prestressing step
Consider introducing tensioning of tendons and simultaneous grouting.
Every n Stage
Grouting takes place at every n stages. If n=1 is entered, the grouting is assumed to take place at the next stage after the corresponding tendons are stressed. If n=2 is entered, the grouting is assumed to take place at the third stage after the two corresponding segments have been stressed.
FCM Tendon Viewer
FCM Tendon Viewer shows the input state of Section and Tendon at Center and Pier Table. In the diagram above, the gray area represents the section at Center and the area enclosed by solid lines represents the section at Pier Table. The dots represent Tendons and the rectangle (
) enclosing a dot represents anchorage. The tool bar icons in the middle signify Zoom all, Zoom window, Zoom in and Zoom out respectively. The mouse wheel is used to Pan the view. The figure below shows a view when the Pan function is executed.
Place the mouse cursor over the dots representing Tendon or Anchorage, and right-click to prompt a tooltip and display Tendon and Anchorage information at the bottom of the View. The user can define colors for Tendon Groups by selecting a Tendon Group from the combo box at the bottom followed by assigning a color.
Tendon Groups are expressed differently for Center and Pier Table as follows:
Center : CSTG, CWTG, ASTG, AWTG
Pier Table : PSTG, PWTG
