CFVR5132 - Bridge model creation

Bridge model creation 2 (with different sections from the CFVR5131 example)

The example is a bridge with the next geometry:
Plan View

Straight line: From MP 90 to MP 120.
Clothoid: From MP 120 (radius = 0) to MP 170 (radius = -200).
Arc: From MP 170 to MP 200 (radius = -200).

Elevation View

Parabola: From MP 90 (0% slope) to MP 200 (5% slope).

It is made of HA-35 concrete. The bridge sections are trapezes with holes.

The aim of the example is to verify the geometry of a bridge.

Element types used in the model: SOLID95

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

The example can be launched on an educational license.
