CFVR2606 - BS 5950-01 Compression and Biaxial Bending

Compression and Biaxial Bending checking according to BS 5950-01

A cantilever steel beam subjected to a Fx load of -50 kN, a bending moment My of 3 kN*m and a bending moment of 8 kN*m applied on one end of the beam.
The beam has a length of 1 m.
The cross section is a HE 200 B.
The beam is made of GRWR50C steel.
The aim of the example is to obtain the cross section classification and the axial and biaxial bending criterion according to BS 5950-01.

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.
