Function
Displays the stress results along the selected design strip direction for the specified load case or load combination. The reported stresses represent the slab's response under the selected loading condition and can be used to evaluate serviceability requirements and stress limits of the post-tensioned slab.
Call
From the Main Menu
select [Post Tension] tab > [Design] group > [Design Result] > [PT Slab Design Result (Stress)]
Input
Load Combination Type
Select the desired load combination type for viewing results.
All Load Combination
Displays results for all load combinations defined under the Serviceability Load Combination option.
Select Load Combination
Initial: Displays results for load combinations defined under the Serviceability Load Combination – Initial group.
Sustained: Displays results for load combinations defined under the Serviceability Load Combination – Sustained group, representing sustained loading conditions used for long-term serviceability evaluation.
Total: Displays results for load combinations defined under the Serviceability Load Combination – Total group, representing the combined effects of all applicable service loads.
Load Cases/ Combination
Select a desired load case, load combination, or envelope case.
Click the ... Button to the right to enter new or modify existing load combinations. (Refer to "Load Cases / Combinations")
Strip Direction
Select the strip direction for which the design stress results will be displayed.
X-Dir: Displays results for design strips defined in the X-direction.
Y-Dir: Displays results for design strips defined in the Y-direction.
Both: Displays results for both X-direction and Y-direction design strips.
Rebar Display Option
Select the slab face for which stress results are displayed along the design strip.
Top: Displays results corresponding to the top reinforcement layer along the selected design strip direction.
Bottom: Displays results corresponding to the bottom reinforcement layer along the selected design strip direction.
Result Option
Select the stress component to be displayed.
Comp.: Displays compressive stress results along the selected design strip direction.
Tens.: Displays tensile stress results along the selected design strip direction.
Fill Options
Controls the visualisation of the selected strip force results.
None: Displays only the force diagram outline.
Line: Displays the force diagram using line-based shading.
Solid: Displays the force diagram using solid shading.
Scale: Specify a scale factor used to magnify or reduce the displayed force diagram.
Type of Display
Define the type of display as follows:
Contour
Display the displacement of the model in contour.
The ...Button
Ranges: Define the contour ranges.
The Customize Range... Button : Assign the color distribution range of contour. Using the function, specific colors for specific ranges can be assigned.
Note
Contour Range Max/Min values can be larger than the max/min output values. If the Contour Range values exceed the output values, they are entered at Rank 0 and Rank 11.
Number of Colors : Assign the number of colors to be included in the contour (select among 6, 12, 18, 24 colors)
Colors: Assign or control the colors of the displacement contour.
Color Table : Assign the type of Colors.
The Customize Color Table Button: Control the colors by zones in the contour.
Reverse Contour: Check on to reverse the sequence of color variation in the contour.
Contour Line: Assign the boundary line color of the contour
Element Edge: Assign the color of element edges while displaying the contour
Contour Options: Specify options for contour representation
Contour Fill
Gradient Fill: Display color gradient (shading) in the contour.
Draw Contour Lines: Display color boundaries in the contour.
Draw Contour Line Only: Display only the colored boundaries of the contour.
Mono line: Display the boundaries of the contour in a mono color.
Contour Annotation: Legend or annotation signifying the ranges of the contour is displayed.
Spacing: Display the spacing for the legnd or annotation.
Coarse Contour (faster) (for large plate or solid model): Represent a simplified contour for a large model using plate or solid elements in order to reduce the time required to represent a complete contour.
Extrude: Where plate elements or solid elements along a cutting plane are represented in contour, a three dimensional contour is created. The positive direction of the analysis results is oriented in the z-axis direction of the local element coordinate system.
The option is not concurrently applicable with the Deformed Shape option. Similarly, the option cannot be concurrently applied to the cases where the Hidden option is used to display plate element thicknesses or the Both option is used to represent Top & Bottom member forces (stresses).
Legend
Display various references related to analysis results to the right or left of the working window.
The ... Button
Legend Position: Position of the legend in the display window
Rank Value Type: Specify a type of values in the Legend and the number of decimal points.
Values
Display the nodal displacements in numerical values.
The font and color of the numbers can be controlled in Display Option.
The ... Button
Decimal Points: Assign decimal points for the displayed numbers
Exp.: Express as exponential
Min & Max: Display the maximum and minimum values
Abs Max: Display the absolute maximum value
Max: Display only the maximum value
Min: Display only the minimum value
Limit Scale (%): Set the screen display limit for nodal displacements relative to the selected maximum or minimum value
Set Orientation: Display orientation of numerical values
Note
The default Decimal Points can be controlled in "Preferences".
Set Orientation = 0 horizontally displays the numerical values to the right of nodes or elements.
The orientation angle represents the counter-clockwise direction, which may be used to enhance the readability of the numbers.
Design Results
Stress Diagram
Displays the stress distribution along the selected design strip direction for the specified load case or load combination.
Include Stress Limit: When enabled, it displays the allowable stress limit together with the stress diagram.
Stress Ratio
Displays the ratio of the calculated stress to the allowable stress along the selected design strip direction for the specified load case or load combination.
