CFVR7316 - Steel checking according to ASME BPVC III Subsection NF

Compression checking of a cantilever steel beam

A steel cantilever beam with W shape section is subjected to a horizontal compression force of 4 MN at free end. Ct reduction coefficient is taken as 0.85
Determine the total criterion according to ASME BPVC III Subsection NF.

Element types used in the model: BEAM188

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

The example can be launched on an educational license.
