STAAD.beava,
the Bridge Engineering Automated Vehicle Application, is an
integrated solution inside the STAAD.Pro environment.
STAAD.beava
uses 3D influence surfaces, which are generated by STAAD.Pro as part
of the loading process.
STAAD.beava will automatically
generate influence surfaces for effects such as bending moments on members,
support reactions, element stresses and nodal deflections.
Fully integrated with STAAD.Pro

Prior to STAAD.beava,
the process of load application for a bridge deck was complex
since governing rules can impose inter-dependant parameters such
as loaded length on a lane, lane factors and load intensity. To
obtain the maximum design effects, engineers had to try many
loading situations on a trial and error basis.
STAAD.beava
helps to reduce the frustration from the trial and error process
and then proceeds to follow the selected design code and calculate
the number of traffic lanes, influence lines along the center line
of the traffic lanes, loaded length along the lanes, critical
locations of all knife, UDL and vehicular loads, and the maximum
and associate effect values. All results are displayed graphically
including the critical position of the vehicle along the traffic
lanes.
All relevant code instructions for loading definitions and
traffic lane calculations are incorporated in
STAAD.beava,
and in cases where vehicle axle arrangements are not standard, it
is possible to define a vehicle and save it in the library for
future analyses. |
