Shell Flexural Design

Function

  • Check the flexural design results for shell elements in contour. Also check the resulting bending moments and the design results of reinforcement along the specified Cutting Lines.

 

Note 
In order to use this function, Eurocode2:05 must be selected in Design > Concrete Design Parameter > Design Code.

 

Call

From the Main Menu select Design > Design > Meshed Slab/Wall/shell Design > Shell Flexural Design

 

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

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).

 

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.
