CFVR5102 - Bridge Stretch


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

  • Straight line: From MP 100 to MP 150.
  • Clothoid: From MP 150 (radius = 0) to MP 220 (radius = 70).
  • Arc: From MP 220 to MP 285 (radius = 70).
Elevation View
  • Straight line: From MP 100 to MP 120 (2% slope).
  • Parabola: From MP 120 (4% slope) to MP 200 (-3% slope).
  • Straight line: From MP 200 to MP 215 (-3% slope).
  • Parabola: From MP 215 (-3% slope) to MP 280 (-1.5% slope).
  • Straight line: From MP 280 to MP 285 (-1.5% slope).
The aim of the example is to verify the geometry of a bridge.
