Instability Tyoe 1, 2 and 3

[Anonymous]

Hello,

I am having issues with instabilities within a cranked beam. However, the beam next to it has the same properties and same releases yet there is no instabilty within that beam.

Does anyone have suggestions as to resolve this issue?

Try to block RZ rotations in supports and RX rotations at both ends for applied bar releases.
