- 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.
- 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
