CFVR5154 - Vehicle loads in a beam bridge model.

The example is a beam bridge where vehicle loads are defined.
The bridge is made of HA-35 concrete.It has a rectangular cross section 30 x 43
The aim of the example is to verify the vehicle loads.

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.
