CFVR1906 - Steel checking according to British Standard 5950 1985

Lateral buckling with moments check of a cantilever steel beam.

A steel cantilever beam is subjected to an axial compression force and moments at free end.
Determine the section class and total criterion, including values of Perry factor and Robertson constant according to BS 5950-85.

Element types used in the model: BEAM4

Needed CivilFEM Modules:
Geotechnical Module
Bridges and Civil Non Linearities Module
Advanced Prestressed Concrete Module

The example can be launched on an educational license.
