To specify either no inplane rotational stiffness or
completely rigid inplane rotational stiffness, use the following procedure.
Typically, the
plate element used in
STAAD.Pro has a very
soft
in-plane rotational, Mz, stiffness. There may be
circumstances where this rotation should be ignored entirely (that is, with
zero in-plane rotational stiffness). Alternatively, there may be circumstances
where a rigid body rotation is required in plate elements.
-
Select the plates which will have the same inplane rigidity.
-
On the
Specification ribbon tab, in the
Specifications group, select either:
To… | Select this
tool… |
---|
ignore the in-plane rotation actions of the
plates |
|
treat the plates as rigid bodies for in-plane
rotation |
|
The
Plate Specs dialog opens to the
corresponding tab.
Note: There are no parameters to
provide for this plate specification.
-
Either:
To… | Do the following… |
---|
add the specification to
the model and assign to the current plate selection |
click
Assign. |
add the specification to
the model for later assignment |
click
Add. |
The dialog closes.
