RTcompositesteel - Modelling and Design of composite steel/concrete bridges for TRIMAS®


  • Classification of cross-section
  • Consideration of secondary effects
  • Load-capacity analyses
  • Serviceability analysis
  • Fatigue analyses
  • Design of bond dowels
  • Cross-section variations
  • Graphical representation of cross-section values and design results

Benefits of RTcompositesteel

The programme component RTcompositesteel fem supports the calculation and design of mixed spatial systems of structural steel, composite steel-concrete or rein-forced concrete bridges and in particular provides the following advantages:

  • Graphic-oriented surface during design with interactive cross section optimisation
  • The calculation / design of the composite girders is performed according to the overall cross section method
  • Simple acquisition of the system, cross section and load histories
  • Consideration of forces of cracking in the concrete chord
  • Automatic evaluation of secondary effects resulting from creep and shrinkage
  • Powerful and economic design according to DIN technical report 104 with a clear result graphic and specific detail information
  • Document output in RTprint / RTF format in compliance with the user’s requirements
