PT Slab Design Result (Strength)

Function 

Displays the design strength results for a PT slab along the selected design strip direction for the specified load case or load combination.

 

Call

From the Main Menu 

select [Post Tension] tab > [Design] group > [Design Result] > [PT Slab Design Result (Strength)]

 

Input

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 strength 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 reinforcement layer for which the strength design results are displayed along the design strip.

Top:  Displays results corresponding to the top reinforcement layer along the selected design strip's direction.

Bottom:  Displays results corresponding to the bottom reinforcement layer along the selected design strip's direction.

Both:  Displays results corresponding to both the top and bottom reinforcement layers along the selected design strip's 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

Select the result type to be displayed for the PT Slab Strength Design.

Applied Rebar
Displays the reinforcement provided (bar diameter and spacing) along the selected design strip direction.

Rebar Length:  When enabled, it displays the reinforcement length and the corresponding number of bars together with the applied rebar results.

Required Rebar Area
Displays the required reinforcement area calculated in accordance with the selected design code.

Include Applied Rebar Area:  When enabled, displays the applied reinforcement area together with the required reinforcement area for comparison.

Required Rebar Ratio
Displays the ratio of the required reinforcement area to the design section area along the selected design strip direction.

Bending Moment Diagram
Displays the design bending moment distribution along the selected design strip direction.

Include Strength Diagram:  When enabled, displays the available flexural strength together with the bending moment diagram.

Resistance Ratio
Displays the ratio of the design demand to the available member resistance along the selected design strip direction. Values greater than 1.0 indicate that the available resistance is insufficient to satisfy the design demand.
