CFVR1103 - EA (MV-103) check: Flexure checking.
Flexure checking according to EA (MV-103) for a pinned-pinned beam.
A pinned-pinned steel beam is subjected to a compression force of 80 Mp and to a Mz bending moment of 80*0.48 Mp*m.
The beam has a length of 6 m.
The cross section is a HE 240 B.
The beam is made of A42 steel.
The aim of the example is to obtain the flexure criterion according to EA (MV-103).
