CFVR5101 - Bridge Stretch

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

Straight line: From MP 90 to MP 120.
Clothoid: From MP 120 (radius = 0) to MP 170 (radius = -80).
Arc: From MP 170 to MP 200 (radius = -80).
Straight line: From MP 200 to MP 300.

Elevation View

Straight line: From MP 90 to MP 150 (3% slope).
Parabola: From MP 150 (3% slope) to MP 200 (-2% slope).

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

Element types used in the model: NONE

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

The example can be launched on an educational license.
