Armored Vehicle Launched Bridge (AVLB) has been analyzed on its load carrying capacity and stability of bracing with theoretical computation, FEA simulation and full-size bridge engineering testing. A new method has been developed out to calculate bending loads used to define and validate required lateral and torsional brace stiffness and strength in beam structure.
In the analyses of strength, stability and testing, the AVLB Military Load Class (MLC) 70 Bridge endured 2500 MLC 85T crossings working load without showing signs of damage or over stressed. It is recommended that the AVLB MLC 70 documentation and signage be updated to MLC 85T (Track) rating for newly converted or overhauled MLC 70 Bridge. Testing of the fatigued bridge could be continued the analysis to develop an inspection and service life indicator, such as Health Monitoring System, to help the sustainment and field maintenance at U.S. Army and U.S. Marines Corps (USMC).
