! SUBTITLE:
!
! DESCRIPTION: A pinned-pinned steel beam is subjected to:
! DESCRIPTION:
! DESCRIPTION:                - compression load of 800 kips applied on the beam ends
! DESCRIPTION:                - bending moment Mz of 400 kips·ft applied on one beam end
! DESCRIPTION:                - bending moment Mz of 200 kips·ft applied on the other end
! DESCRIPTION:
! DESCRIPTION: The beam has a length of 240 in.
! DESCRIPTION:
! DESCRIPTION: The cross section is a double T W 27x84.
! DESCRIPTION:
! DESCRIPTION: The beam is made of GB 50017  Q390 steel.
! DESCRIPTION:
! DESCRIPTION: The aim of the example is to obtain axial + bending
! DESCRIPTION: checking criterion according to GB50017.
