Input
Load Cases/ Combinations
Select a desired load case or load combination. Click the ... Button to the right to enter new or modify existing load combinations. (Refer to "Static Load Cases / Combinations")
Flexural Design
Select to check the flexural design results for a shell.
Element : Display the automatic design results using the internal forces calculated at each node of the element.
Avg. Nodal : Display the automatic design results using the average internal nodal forces of the contiguous elements sharing common nodes.
Element : Depending on the selected option above (Element or Avg.Nodal), produce the automatic design results for moments at each node of the elements that define the shell.
Width : Depending on the selected option above (Element or Avg.Nodal), produce the automatic design results using the average of the moments in the shell elements that contain the selected node.
Top : Design top bars for negative moments.
Bottom : Design bottom bars for positive moments.
Both : Produce the larger of the Top and Bottom bars.
Rebar (Dir. 1) : Display the shell design results for the reinforcing steel entered in Dir. 1.
Rebar (Dir. 2) : Display the shell design results for the reinforcing steel entered in Dir. 2.
Concrete : Display the shell design results for Concrete
Type of Display
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).
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.
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.
Components
Membrane Axial Force : Display the axial forces per unit width of the top/ bottom layers of the sandwich model.
Membrane Shear Force : Display the in-plane shear forces per unit width of the top/ bottom layers of the sandwich model.
Rebar Stress : Display the tensile stresses of reinforcement.
As_req(mm^2/m) : Display the area of the required reinforcement.
Rho_req : Display the required reinforcement ratio.
Rebar Arrangement : Display the bar spacing in contour, which is placed in the plate elements using the standard bar sizes defined in the ‘Slab/ Wall/ Shell Rebars for Checking’ menu.
Resistance Ratio : The ratio of the design moment to the moment resistance when the designed rebar spacing is applied.
Operations
The Design Result Text Output Button : Produce the detail flexural design results of shell elements in a text format.
The Design Result Table Button : Produce the flexural design forces of shell elements in a tabular format.
