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
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
and select an option to enter a desired number.
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 and select an option
to enter a desired number.

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 .
Copy Node
Attributes
Select the option whether to copy the nodal attributes during the copy
process (nodal boundary conditions, nodal concentrated loads, etc.). Click
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 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 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
First, create a
reference frame, which will become a basis for subsequent copying operation.
Using the copy conditions
of Building Generation, generate copy conditions considering only the
story heights.
'3' in Number of Copies, '11.5' in Distance

'4' in Number of Copies, '13' in Distance

Copy condition table is created as follows
:
Click
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.
Click , then the material property and section increments are reflected
in the copy condition table below.
Select the elements
to be copied and click 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.
