CFVR7327 - Steel checking according to ASME BPVC III Subsection NF

Tension & bending checking of a cantilever steel beam

A steel cantilever beam with TS box shape section is subjected to a tension axial load and a vertical force in both directions 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.
