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.

FINALLY, A COMPLETE BRIDGE ANALYSIS AND DESIGN PACKAGE

Introducing the New Bridge Loader Module for STAAD.Pro

STAAD.beava

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.
