CFVR7322 - Steel checking according to ASME BPVC III Subsection NF

Bending checking of a standard steel beam

A steel simply supported beam with built-up T shape section is subjected to a vertical force at middle span. 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.
