CFVR1101 - EA (MV-103) check: Tension checking according EA.

Tension checking according to EA (MV-103) for a pinned-pinned beam.

A pinned-pinned steel beam is subjected to an axial tensile force of 70.8 Mp.
The beam has a length of 5 m. the cross section is a UPN 180 with 3.36E-4 m² of holes area.
The beam is made of A42 steel.
The aim of the example is to obtain the tension criterion according to EA (MV-103).

Element types used in the model: BEAM3

Needed CivilFEM Modules:
Geotechnical Module
Bridges and Civil Non Linearities Module
Advanced Prestressed Concrete Module

The example can be launched on an educational license.
