CFVR1002 - Eurocode 3 1992 test: Pure bending
Bending check according to Eurocode 3 1992
A pinned-pinned steel beam is subjected to a distributed load of 2.75kN/m
The beam has a length of 12 m. the cross section is an IPE 200.
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 bending checking criterion according to Eurocode 3 1992.
