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.
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.
