Activate or deactivate the buckling check for steel or timber beams that are subjected to compression

In the 2020.e version, an option has been implemented to activate or deactivate the buckling check for steel or timber beams that are subjected to compression in the XY plane and in the XZ plane (in CYPECAD only beams that are disconnected from the rigid diaphragm can be subjected to compression). In previous versions, compressed steel or timber beams were always checked for buckling.
