To assign a support that acts inclined with respect to
the global axis, use the following procedure.
You may want to
change the length unit to a more convenient value if you are going to define an
incline direction by coordinate or vector.
See
Inclined Support Axis System
for details on how the reaction directions are determined from the reference
coordinate.
-
Select the nodes that will have the same support condition.
-
On the
Specification ribbon tab, select the
tool in the
Supports group.
The
Create Support dialog opens to the
Inclined tab.
-
Select the method for specifying the
Incline Reference Point:
To use this
reference… | Do… |
---|
an arbitrary point with respect to the supported
node |
select the
Coordinate option and then type the
relative global X, Y, and Z distances to the reference point |
an arbitrary point with respect to the model
origin |
select the
Ref option and then type the global X, Y,
and Z coordinates |
an existing node in the model |
select the
RefJt option and then select the node
number from the drop-down list |
Note: If you select the
Ref or
RefJt options, then the orientation of the
inclined support axis system may vary from node to node.
-
Select the
Support Type to use.
-
Pinned - restrained against translation
but free to rotate
-
Fixed - restrained in all degrees of
freedom
-
Fixed But - released in specified
degrees of freedom and can have spring constants assigned in restrained degrees
of freedom
-
Enforced - restrained in all degrees of
freedom and can have imposed support displacements assigned as loads
-
Enforced But - released in specified
degrees of freedom and can have imposed support displacements assigned as loads
- Optional:
For
Fixed But support type, type linear spring
constants to use as necessary.
-
For
Fixed But or
Enforced But support types, select the
released degrees of freedom.
-
Either:
To… | Do the following… |
---|
add the support type to the
model and assign to the current node selection |
click
Assign. |
add the support to the
model for later assignment |
click
Add. |
The dialog closes.
