Programme component TRIMAS® fem in order to process composite steel-concrete bridges according to DIN technical reports 101-104, EC1-EC4, EN 1991-EN 1994 and according NADs for DE, UK, CZ/SK, AT
Programme component for general structures with Windows®-oriented working environment for processing composite steel-concrete bridges according to the DIN technical reports 101-104, EC1-EC4, EN 1991-EN 1994 and according NADs for DE, UK, CZ/SK, AT for general spatial FE-Systems incl. framed structures. The application supports the following input, calculation and design options for general systems of composite steel-concrete:
- Open, welded I - steel girder cross sections and open, i-shaped drum girder cross sections made of structural steel with concrete chords as track supporting plate
- Steel cross section can consist of three top chord, web and bottom chord cross sections each
- Concrete chord with up to 5 partial cross sections of different inclinations
- Creep and shrinkage is treated according to the overall cross section method
- Cross section stages (variants) for different load states (long-time loads, short-time loads and secondary loads)
- For each cross section state both the overall cross section values and the effective cross section values for edge field, edge support, infield, inside support, are evaluated
- Result graphics for geometry with dimensions, chord thicknesses and effective widths
- Calculation of the transformed, elastic cross section values with the relevant reduction factors and the plastic cross section values
- Application of the effective slab areas according to the DIN technical report, EC & EN
- Application of the cracked areas according to the DIN technical report, EC & EN
- Variant technique, allocation of the variants per line in the construction stage
- Variant technique, alteration of the variants per line over all construction stages
- Superposition according to DIN technical report, EC & EN
- Graphical detail illustration at the system
In the limit states of bearing capacity, fatigue, serviceability and the safety of bonds, the following analyses are performed according to the DIN technical report 104:
Calculation of secondary effects
- Automatic evaluation of equivalent temperature dummy loads
- Creep resulting from concreting and finishing loads (PT loads)
- Creep resulting from column settlement or regular deformation (D loads)
- Primary and secondary shrinkage (S loads)
Limit state of bearing capacity other than fatigue
- Cross section classification
- Plastic and elastic moment bearing capacity
- Moment bearing capacity with limited strain
- Plastic shear force bearing capacity
- Normal force – moment -shear force-interaction
- Web plate bulging induced by flange
Limit state of bearing capacity fatigue
- Range of stress structural steel equivalent to damage
- Range of stress reinforcement steel equivalent to damage
- Fatigue concrete due to pressure
Limit state of serviceability
- Limitation of stress structural steel
- Limitation of stress reinforcement steel
- Limitation of stress for concrete pressure
- Minimum reinforcement (first cracking)
- Terminated cracking
- Quasi-permanent deformations
Securing of bonds
- Dowel bearing capacity
- Dowel cover in LSBC
- Dowel cover in LSS
- Structural design of the dowelled joint
- Dowel fatigue
Cross section optimisation
- Alter partial cross sections from existent cross sections in the design
- Exchange cross sections in the design
- Apply new cross sections in the design and subsequently exchange them
- Immediate new calculation of cross section values and subsequent analysis / design
