CFVR7904 - CTE DB SE-A test: Bending and shear

Bending and shear checking according to CTE DB SE-A

A fixed steel beam subjected to a surface load of 1000 kN/m.
The beam has a length of 1 m.
The cross section is a IPE 400.
The beam is made of Fe 430 steel which has a fy of 275000 kN/m2.

The aim of the example is to obtain the cross section classification and shear criterion according to CTE DB SE-A.

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.
