CFVR7515 - Steel checking according to ANSI AISC N690-1994

Tension & bending checking of a cantilever steel beam

A steel cantilever beam with built-up I shape section is subjected to a tensile axial load and a vertical force in both directions at free end.
Determine the total criterion according to ANSI AISC N690-1994.

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.
