Building Generation

 

 

 

Copy existing nodes and elements of given conditions to create structural frames of high-rise buildings.

 

 

 

From the Main Menu select Model > Building > Building Generation.

 

Select Geometry > Building > Building Generation in the Menu tab of the Tree Menu.

 

Shortcut key : [Ctrl]+G

00-Check.jpg Start Node Number

 

Assign a starting node number of new nodes that will be created with new elements in the Model Window. This number is automatically set to the largest node number currently used +1. Click 00-Point.jpg and select an option to enter a desired number.

 

 

00-Check.jpg Start Element Number

 

Assign a starting element number of the newly created elements. This number is automatically set to the largest element number currently used +1. Click 00-Point.jpg and select an option to enter a desired number.

Number of Copies : Number of stories to be copied

 

Distance (Global Z) : Copy distance in GCS Z-direction (Story height)

 

Material Inc. : Increment for Material property numbers to be created

 

Column Section Inc. : Increment for Column Section numbers to be created

 

Beam Section Inc. : Increment for Beam Section numbers to be created

 

Brace Section Inc. : Increment for Brace Section numbers to be created

 

Wall Section Inc. : Increment for Wall Thickness numbers to be created

 

 

00-Check.jpg Operation

 

03-BG-2.jpg : Enter or add Z-direction copy conditions

 

03-BG-3.jpg : Modify previously entered copy conditions

 

03-BG-4.jpg : Delete previously entered copy conditions

The copy conditions entered in the above Building Generation are displayed by stories in a table.

 

 

Note
When the increments for material properties or section numbers are widely varied, specify the copy conditions considering only the story heights first. Then, reflect the increments for material properties or section numbers in 03-BG-5.jpg.

 

 

Copy Node Attributes
Select the option whether to copy the nodal attributes during the copy process (nodal boundary conditions, nodal concentrated loads, etc.). Click 00-Point.jpg to copy attributes selectively.

 

Copy Element Attributes
Select the option whether to copy the element attributes during the copy process (element boundary conditions, element loads, etc.). Click 00-Point.jpg to copy attributes selectively.

 

Copy Building Attributes
Select the option whether to copy the building attributes during the copy process (Rigid Link and Assign Floor Loads, etc.). Click 00-Point.jpg to copy attributes selectively.

Enter the merging tolerance in terms of a distance for merging newly created nodes and existing nodes.

 

 

Note

Application example for Building Generation

 

    1. First, create a reference frame, which will become a basis for subsequent copying operation.

 

 

 

    1. Using the copy conditions of Building Generation, generate copy conditions considering only the story heights.

 

'3' in Number of Copies, '11.5' in Distance + 03-BG-2.jpg

 

'4' in Number of Copies, '13' in Distance + 03-BG-2.jpg

 

Copy condition table is created as follows :

 

 


    1. Click 03-BG-5.jpg to reflect the increments for material properties and section numbers by stories in the copy conditions. Increments for section numbers by different types of members (column, beam, brace, wall) can be separately selected.

 

 

 

 

    1. Click 03-BG-10.jpg, then the material property and section increments are reflected in the copy condition table below.

    1. Select the elements to be copied and click 03-BG-12.jpg to create a building model as shown in the figure.

 

 

The Application example of the Install CD explains the procedure of using Building Generation to create Steel (15 stories) and RC (12 stories) structures.

 

Building Generation can be applied to complicated structures whereby, story heights, materials, sections and thicknesses vary from floor to floor. Only one copy operation is all that is required.
