CFVR1001 - Eurocode 3 1992 test: Cross section classification.
Cross section classification checking according Eurocode 3.
A cantilever steel beam which has different sections is subjected to an axial compression force of -1 kN. The beam has a length of 5 m which is divided in four segments of 1.5 m. The first segment of the beam has an IPE 100 section, the second one has an IPE 160 section, the third one, an IPE 200 and the last one, an IPE 240.
The beam is made of S 460 steel which has a fy of 460000 kN/m2.
The aim of the example is to obtain the cross section classification according to Eurocode 3 1992.
