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 centerline
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.
