M. To assign inplane rotation behavior to plates
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 -
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.
