Introducing Structural Analysis

  • There are two analysis model types that can provide for a variety of structural solutions ranging from simple line beams and portal frames to complex three dimensional shell finite element structures.
    1. Line Beam - a line beam is useful for global and preliminary analysis. No axial, torsion or out-of-plane effects are considered, so this type is not appropriate for curved or highly skewed structures.
    2. Refined Analysis - advanced framework, grillage and finite element analysis.
  • The structure geometry is defined graphically using 'real' objects such as setting out lines, carriageways etc. instead of 'imaginary' objects such as nodes and elements.
  • Complex geometry can be exported to and imported from Autodesk® AutoCAD with the DXF interface.
  • Structural components can be defined using Design Sections and Design Beams so that complex properties are automatically calculated and assigned.
  • Optimum vehicle load patterns can be generated to BD/37, BD/21, BD/86 and BS5400 railway loads.
  • Analysis results are easily used by the Design Beams for code checking.
  • There are a number of advanced analysis features, such as:
    1. Virtual members containing beam/shell elements with composite results.
    2. Reinforcements moment calculations for slabs (Wood/Armer and Denton/Burgoyne methods).
    3. Lift off supports and tension/compression only members (non-linear analysis).
    4. Application of prestressing tendons with complex profiles which provides corresponding load effects, taking into account all losses in prestress.
    5. Staged construction.
  • All results can be displayed graphically and in a tabular form (which can be printed).
  • Tabular results can be exported directly to a spreadsheet.
  • A project can contain (only) one Refined Analysis model and any number of Line Beam models. For example, a refined model could be defined for the detailed effects, and a line beam model for the inner beam line and another line beam model for the outer beam line, used for conceptual analysis, or to obtain temperature and shrinkage analysis effects.
