Steel/concrete box girder

• 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

The programme component RTcompositesteelbox fem supports the calculation and design of spatial box girder systems of structural steel, composite steel-concrete or reinforced 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
