Function
- Move more than two nodes and auto-generate elements between the moved nodes.
- This function is useful for copying or moving cable elements in 3 dimensions after creating cable elements connecting the main girder with the tower of a cable stayed bridge. Until now, in a cable stayed bridge model, we were generating cable elements after creating a Rigid Link between the tower/main girder and the anchorage. However, using this function, cable elements can be directly created between the tower and the main girder, and when the distance between the tower/main girder and the anchorage is entered, the cable elements are auto-generated in 3 dimensions.
Call

Input
Create Eccentric Elements dialog box
Click
to the right of Create Eccentric Elements

Start Number
Node Number
Assign a number to the new starting node created together with new elements in the Model Window. This number is auto-set to the largest node number in use +1. To modify this item, click and select an option to specify a desired number.
Element Number
Assign a new starting element number. This number is auto-set to the largest element number in use +1. To modify this item, click and select an option to specify a desired number.
Mode
Copy : To copy elements
Move : To move elements
Translation
Enter the eccentricities of i-end and j-end with respect to GCS.
GDXi : Component of the eccentricity vector at I-end in the GCS X-direction
GDYi : Component of the eccentricity vector at I-end in the GCS Y-direction
GDZi : Component of the eccentricity vector at I-end in the GCS Z-direction
GDXj : Component of the eccentricity vector at J-end in the GCS X-direction
GDYj : Component of the eccentricity vector at J-end in the GCS Y-direction
GDZj : Component of the eccentricity vector at J-end in the GCS Z-direction
Material Inc.
An increment for material property numbers while copying elements
Rep. : Check this box to enable automatic material number incrementation with a specified increment value each time replication is performed.
Section Inc.
An increment for section numbers while copying elements
Rep. : Check this box to enable automatic section number incrementation with a specified increment value each time replication is performed.
Boundary Group of Rigid Link
Select a Boundary Group of Rigid Link to be generated at both ends of eccentric elements. Click to define a boundary group or modify an existing boundary group.
Copy Node Attributes
Select the option whether to copy the attributes (nodal boundary conditions, nodal concentrated loads, etc.) to the nodes being copied. Click to assign desired attributes selectively.
Copy Element Attributes
Select the option whether to copy the attributes (element boundary conditions, element loads, etc.) to the elements being copied. Click to assign desired attributes selectively.
