CFVR5211 - 2 Span prestressed beam.


The model is a straight prestressed beam of 20 m length.
The beam is made of C20/25 concrete and the tendons are made of Y1860C steel.
The cross section is rectangular, 1 x 2.
The aim of the example is to verify the tendons generation.

Element types used in the model: BEAM44

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

The example can be launched on an educational license.
