! TITLE: CFVR7911 - CTE DB SB-A test: Compression and flexural Buckling
! SUBTITLE: Compression and flexural Buckling checking according to CTE DB SE-A
!
! DESCRIPTION: A fixed steel beam subjected to a Fy load of -250 kN, a bending
! DESCRIPTION: moment Mz of 50 m*kN and a bending moment Mx of -30 m*kN
! DESCRIPTION: applied on the end of the beam.
! DESCRIPTION:
! DESCRIPTION: The beam has a length of 1 meter.
! DESCRIPTION:
! DESCRIPTION: The cross section is a IPE A 550 .
! DESCRIPTION:
! DESCRIPTION: The beam is made of Fe 460 steel which has a fy of 460000 kN/m<sup>2</sup>.
! DESCRIPTION:
! DESCRIPTION: The aim of the example is to obtain the cross section classification and compression
! DESCRIPTION: and flexion buckling criterion according to CTE DB SE-A.
