CFVR1102 - EA (MV-103) check: eccentric compression according to EA.
Eccentric compression 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*60E-3 Mp*m.
The beam has a length of 4 m. The cross section is a T section with the following dimensions:
- A = 5.587E-3 m2.
- Wy = 106.667E-6 m3.
- Wz = 171.01E-6 m3.
- Wpy = 156.667E-6 m3.
- Wpz = 298.35E-6 m3.
The aim of the example is to obtain the compression criterion according to EA (MV-103).
