Abstract

ABSTRACT
Recently, The military load capacity 70ton (MLC70) became the designable load for military bridges
after the upgrading of the military vehicles and tanks according to military code. The analysis of
pontoon bridges requires the analysis o f units of the floating bridge in separated stages as a unique
pontoon, bridge bay (ferry) and finally the bridge as a whole, taking in consideration for each stage the
critical cases of loading and stability limits.
This paper presents a study for the be st method for bridge upgrading from MLC60 to MLC70 using
3D FEM by ANSYS software package version 11.0 for a different five proposals for the development of
the existing ferries, taking in consideration the critical vehicle positions during loading at the middle of
the water barrier.
