Time History Calculation with RF-/DYNAM Pro - Walking and Running over a Footbridge

Online presentation

Content

Duration: 1:03:14

Contents:
  • Features of the RF-DYNAM Pro Module
  • Time course analysis, natural frequencies and mode shapes
  • Theory of walking and running (formulas according to Prof. Bachmann)
  • Example in RFEM: Load cases with RF-MOVE Surfaces
