M. To assign an enforced support
To assign a support which can have a support displacement imposed as a load, use the following procedure.
In
STAAD.Pro, a special support type is used for
supports that will have an imposed displacement as part of a load case. These
are called
"enforced" supports.
- Select the nodes that will have the same support condition.
- On the Specifications ribbon tab, select the tool in the Supports group.
-
Select one of the drop-down support types as follows:
Support condition… Select the following other support… fixed in all degrees of freedom Enforced released in one or more degrees of freedom Custom Enforced To impose a displacement on a joint with releases (e.g., a "pinned" support), you must use a custom enforced (i.e., ENFORCED BUT) support type and define the released degrees of freedom.
The Create Supports dialog opens to the corresponding tab. - (Optional)
For an enforced but support type, check the
Releases for this support type.
For example, to create a "pinned" type support, you would check the MX, MY, and MZ release options.
