CFVR2954 - Shear checking plus axial force according to SP 63.13330.2012

Check a reinforced concrete beam subjected to shear force and axial force according to SP 63.13330.2012

A pinned-pinned beam has a rectangular reinforced concrete section, and it is subjected to a uniform distributed load of 150 kN/m and different axial N forces. The length of the beam is 5m. The aim of the example is to obtain the check criterion according to SP 63.13330.2012.

Element types used in the model: BEAM3

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

The example can be launched on an educational license.
