• Generation of critical patterns of vehicular loads producing extreme effects in structural components
• 3-D influence surface diagrams for design optimization and quick results verification
• Full integration with STAAD.Pro. STAAD.beava generated loads can be easily merged with any other live or dead loads defined in the model, where each loading pattern represents a STAAD.Pro load case.
• Support for AASHTO 2000 (ASD, LFD and LRFD), UK BS5400 Part II, and IRC:2000 Bridge Design Specifications with all relevant code provisions for loading definitions and traffic lane calculations incorporated.

Create STAAD load cases based on critical loading patterns within STAAD.Pro

• Roadway definition can be completed in a few easy steps. Flexible user interface allows creation of straight, curved or custom-defined roadways on flat and superelevated decks of any shape.
• Traffic lanes are automatically created. Alternatively, fully customizable lanes may be specified by the user.
• Vehicle Database includes pre-defined loadings (H, HS, and HL designations). User-defined loadings may be added to the Database as needed.
• Load application algorithms include transverse movement of loads, jack-knifing of trucks within curved lanes, turning off axles not contributing to extreme effects.
• Program calculates the following:
  • number of traffic lanes,
  • width and length of traffic lanes,
  • positions of truck or tandem wheels within lanes,
  • size and locations of uniformly distributed loads,
  • locations of concentrated loads,
  • values of responses for critical loading conditions.
• Output in any unit system.
• Powerful, intuitive graphical user interface. Loading patterns can be shown graphically on the model.
• All results are easily accessible through an integrated load browser. A complete text output is also available.
